UltraESB: UltraESB v1.6.2 released!

2011-12-09T10:08:00.001+05:30

UltraESB: UltraESB v1.6.2 released!: AdroitLogic Private Ltd. announced today the release v1.6.2 of its free and open source Enterprise Service Bus, the UltraESB. The UltraESB is released under the OSI approved GNU Affero General Public License; as well as a zero-dollar non-GPL commercial license which allows unlimited and perpetual production use free of charge. First released in January 2010, the UltraESB was the first ESB to utilize memory mapped files and zero-copy, coupled with non-blocking IO to provide extreme levels of performance.

The improvements contain;

Improved file handling in file cache
Fix the issue with starting the sample configurations in Windows based systems
Enhanced logging to remove error logs, which are not errors from the ESB users point of view
Fix to stop the server if a compilation failure or configuration error is detected in the dynamic sub context at the startup - Fix to acquire the ZooKeeper session and close it properly in a startup just after an abnormal stop of the server
Enhanced JMS transport to simplify the implementation of Guaranteed-Delivery pattern
Improved REST proxying support when a JMS intermediary is used for guaranteed delivery

UltraESB adds support for the routing and mediation based on Protocol Buffers

2011-12-06T16:18:00.001+05:30

Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages – Java, C++, or Python.

UltraESB is the best ESB in usability, performance and extensibility. As many organizations are now moving to protocol buffers to take advantage of its performance and multiple language support, it has been the right time that we introduced support for routing and mediating such messages based on protocol buffers.

In the first step, UltraESB has implemented two key features.

The support to read a protocol buffers based message during mediation as a Java object, to make routing decisions, logging, auditing, persistence to a Database etc.
The support to alter the message based on protocol buffers after any updates.

Both these features have already been implemented on the trunk and now available for you to try out from the nightly build with the sample 302.

While it is possible to parse the message without the generated protocol Java type classes, it is also possible to provide the generated type classes and get hold of the exact type object so that the user can use the protocol buffer semantics to read/alter the message and set it to back to the message in the mediation.

Even if you parse a protocol buffers based message, yet do not alter it - no serialization overhead will be incured, as the UltraESB will detect that the message (although parsed) was not modified, and when proxying, directly use the original bytes stream that it received from its client to send out to the desired endpoint again. This enables the routing of parsed protocol buffer messages, based on protocol buffer content with the least possible overhead, in the same way as how the UltraESB achieves high performance for XML/SOAP, JSON, Hessian etc content based routing.

This is just the start of the protocol buffers support with the UltraESB. Automated protocol buffers conversion to / from other message formats will soon be available such as:

XML/POX/SOAP to protocol buffers conversion and vice versa - enables the user to integrate new protocol buffers based services with legacy XML or SOAP services
JSON to protocol buffers conversion and vice versa - enables the user to integrate protocol buffers based back-end services with JSON front ends easily
HTML to protocols buffer conversion and vice versa - enables the user to efficiently transfer HTML using protocol buffers as the wire format.

Further to these, regular expression based routing without parsing the protocol buffer messages will also be possible in future in a very efficient manner.

Digital Content and Service Provider Jesta Digital Migrates to the UltraESB

2011-11-28T14:37:00.001+05:30

Better design and usability, maintainability is what most of the users want from a solid ESB, not hypothetical features or requirements.

Jesta Digital migrates to UltraESB because of its simplicity, design, usability, extensibility, maintainability and of course because of its industry leading performance.

"In a very demanding and rapidly changing market it is of utmost importance to be able to quickly adjust the technical platform to support product innovation and change. The UltraESB was able to demonstrate to the Jesta Digital Technology team in Berlin that its simplicity, testability, extensibility and performance is made for a matching foundation" said Eric Hubert, the Executive Director of Strategy and Architecture at Jesta Digital.

Want to know more on the reasons for there migration, check out the case study.

"It was a great pleasure to work with subject-matter experts who combined first-hand knowledge, passionate work on their product and dedication to tackle the customer's challenges"

UltraESB - designed for Future

UltraESB 1.6.1 released!

2011-10-30T13:52:00.001+05:30

The UltraESB is now getting even more traction from among enterprise users. However, we will not keep maintenance releases away from any of our free and open source users, and will frequently publish new releases as we enhance the product. The 1.6.1 release enhances the 1.6.0 release from a month back as follows

Enhancements to the HTTP/S transport
Improved error handling within the mediation layer
Introduction of the "mediation.response" built in endpoint
Zabbix template registration made asynchronous

Any 1.6.0 user of UltraESB is free to upgrade. Download and try it out.

While our approach is to release frequently and often, the maintenance releases further shorten our release cycles. How ever from the key features and functionality 1.6.1 release is very close to that of 1.6.0. Well, that is how maintenance releases has to be. So migrating from 1.6.0 to 1.6.1 is just a matter of changing the binaries. If you need any assistance on migration, please drop us a note on info@adroitlogic.com.

UltraESB documentation released recently has been enhanced and the current live documentation is for the 1.6.1 release.

UltraESB Documenation

2011-10-17T15:33:00.000+05:30

AdroitLogic has released the first phase of the official documentation for the UltraESB. This documentation is a complete reference of the UltraESB product and the associated tools.

Formula 1 of ESB - Round 5, with 8 open source products

2011-10-04T22:10:00.000+05:30

Formula 1 has been the race all the racers are waiting for and it has become the worlds most attracted race.

F1 racer on the race

ESB performance has been equally discussed, interesting topic in the IT industry. esbperformance.org and the performance test kit described by it has become the de-facto standard of the ESB performance testing.

This time, the round #5 shows that the UltraESB has been taking the lead on every front. The other 7 open source ESB's that is being tested are as follows.

WSO2 ESB
Mule ESB CE
Apache ServiceMix
Fuse ESB
Talend ESB SE
JBoss ESB
Petals ESB

The performance test scenarios has been updated to include 2 more CBR (Content based routing scenarios) forming the 6 scenarios used as follows;

Direct proxying
Message body content based routing
Message header content based routing
Transport header content based routing
XSLT trannsformation
WS-Security proxying

The observations are as follows;

Few facts observed are as follows;

UltraESB is taking the lead in all fronts
WSO2 ESB has improved security performance with compared to previous times
Some of the ESB's were not being able to handle the load, WSO2, Mule and Talend were able to finish the race with UltraESB.

Coming back to car racing, I loves to drive fast, and interested about anything faster. :-) That is why I love ESB performance and to see the product I work on ranked at 1st in performance. I will be driving the UltraESB exactly like how I drive my car to beat all the others, yes it is fun, test me either on the road or on the Linux Servers. ;-)

UltraESB introduces, live update with zero downtime

2011-09-27T17:51:00.000+05:30

Did you ever thought of an ESB that could do live configuration update? The first answer for this would be "Haah.. yeah I do. I know many systems which support that". Think twice about what they offer, most of the time they offer hot deployment or hot update of the configuration artifacts or the configuration versioning.

Think of what will happen to the messages in-flight if you do not put the server into a mode which does not accept any more messages and do the configuration update, after you processed all the accepted messages. You will consistently be using the same configuration for all the messages, if you do the above. The catch with that approach is that it introduces a downtime, but it guarantees the correctness. If you do not follow this approach, ESB is at an unknown state from the messages point of view, as the message will see different configurations through its life-cycle.

"Now, the world is evolving, and the technology should too.. So do you want to stick to that same technique?". We at adroitlogic asked this question from our selves. I must mention hear that the original thought actually was initiated by a smart enterprise user of the product. We found that, a good architecture and design would allow us to do the configuration update without any downtime yet guaranteeing the absolute correctness.

The next task was to see if we have the right design to implement this on our ESB which has the identifier UltraESB, and we found we do have the just right design for that, and we implemented that.

So with UltraESB 1.6.0, the latest release which went live today contains this feature and you can try it by downloading the release from adroitlogic downloads page.

The implementation guarantees that the updating configuration is prepared as a new configuration and at the point it is available, it is used to dispatch the new messages, while the old configuration will be used to process any accepted messages before that point. The logic is quite simple but implementation could be really hard if not, impossible on an ESB which doesn't think of this from the design itself. This again emphasises that the UltraESB is the future ESB.

With that I would like to introduce the new release of the UltraESB which has the following enhancements and features in addition to this.

Failover nodes automatically, in a clustered deployment
Introduction of the minimal distribution (nearly 6MB)
Ability for a server to run as another server
Improved connection debug information
New theme for the UConsole
New commands on UTerm, allowing the server management
Custom password encryption utility
and many more enhancements...

Stay tuned for more information on the new features of the 1.6.0 release of the UltraESB.

Head dump of UltraESB

2011-09-22T15:03:00.000+05:30

As I wrote earlier lastweek, I have taken up the responsibility of making the UltraESB aneven better product! It is really a challenging task as it is alreadythe best ESB I have ever seen. In this post, I am trying to get ahead dump of me about the UltraESB, based on my initial experience inthe past few days.

To start with, it is a greatopen source project where the code is publicly shared on bitbucket at[1], and is developed with lots of feedback from its actualenterprise users! It is not just a typical ESB rather it is an AS2switch, JSON/Data Services and Mock Service container, Securitygateway, Layer7 router and much more.

Best in Performance

As per currently publishedstatistics, the UltraESB is the best performing open source ESB.AdroitLogic is continuously testing performance over all the majoropen source ESB's to make sure it keeps up with any improvements thatother ESBs are doing, and publishes all the results openly at ESBPerformance site. AdroitLogic is sharing all the configurations,materials and pre-configured EC2 images to let any third party runthese performance tests themselves and see the difference, which willbe very handy when evaluating ESBs.

Ease of configuration/development

Being the best inperformance is not enough to become the best ESB. The other keyaspect that I see in UltraESB is that the ease of configuration. Tobe frank, initially, I didn't believe that writing mediation logic inJava is the best way to make the configuration easier. Later I foundthat it is very convenient with compared to an ESB with a custom DSL.The problem with custom configuration languages is that you have tolearn the language and then learn how to apply that language to solveyour integration problem. UltraESB, on the other hand, gives you theability to solve your integration problem in Java or any otherscripting languages like JavaScript, Ruby, Groovy, etc... Now you donot have to learn the language as you most of the time are alreadyfamiliar with at least one of these languages, and you canconcentrate on applying the language you know to resolve yourintegration problem with the very simple mediation API [2].

IDE integration and tooling

Another advantage ofUltraESB over the other ESBs is the seamless integration with yourdevelopment environment. If you know Java, you probably know how towork with Intellij IDEA, Eclipse, or NetBeans IDE. UltraESBintegrates nicely with all these 3 development environments andprovide the ability to develop, run and debug (step throughdebugging) your integration solution within the IDE itself. If youjust give it a try, you will realize how effective it is in solvingyour integration problem, rather than spending time on understandingthe languages and how to setup this and that. You can find enoughmaterials on the AdroitLogic site on the development environmentIntegration, for example [3], [4], [5], and on the YouTube adroitlogic channel.

You do not have to learnanything you can just get started. Seriously, this will reduce thedevelopment time drastically, at least by 60% even if you havealready mastered the custom configuration language that you are usingwith the other ESBs. This is because of the capability to run/debugthe solution that you are developing within the IDE without building,deploying, etc... This is why I say it is the Future ESB, withUltraESB developing your integration solution will be exactly same aswriting "Hello World" with Java and running/debugging thenimprove it and shaping it up towards the final solution.

Manage/Monitor deployments
All that is about the development phase, now what about the deployment and maintenance? UltraESB ships many options to manage and monitor the deployed UltraESB instances.

JMX monitoring and management via JConsole or any external tool
UConsole, a web based console to monitor and manage the instances
UTerm, a terminal client to manage the ESB, System Administrators loves this idea and using the terminal commands to manage the UltraESB
Zabbix monitoring with alerts and notifications for SLA management andescalation

All these mechanisms gives the best set of features to manage deployed UltraESB individual instances as well as a complete cluster.

Better by Design

The internal design, though most of the users of the product do not care that much, is the secret behind the success of the UltraESB. The beautiful architecturebehind this great product makes things simple to develop, use andextend further as required. For example, the native Springconfiguration support allows one to integrate with almost any otherexternal system seamlessly! A few of the powerful and advancedfeatures visible to end users is as follows;

Zero-copy proxy with memory mapped / RAM disk based IO giving extreme performance
Zero down time graceful configuration update (other ESBs do have hotdeployment/update, which they recommend to turn off in productiondeployment ;-), this is way more than that!)
Cluster wide management and failover capability for nodes in the cluster (If "nodeA" of the cluster fails, the "nodeB" on the same cluster can automatically take over "nodeA", until it comes back live)

Becoming the best ESB is/was easy but being there is what's important and more difficult. I treat it now my duty to continue to give the best ESB to the users, with UltraESB.

Give it try, and go for a test run with UltraESB to see more...

Past, Present and now the Future ESB

2011-09-13T13:30:00.000+05:30

I've seen the Past of the ESBs, contributed to develop the Present, and now will be a part of the ESB of the Future!

I'm thrilled to announce today that I have joined AdroitLogic as its Director of Engineering! AdroitLogic is the company building the free and open source UltraESB, founded by the first architect and product manager of the WSO2 ESB, Asankha Perera. I've known Asankha from 2006, and worked with him from the day I joined WSO2 until the day he left. After his departure I took over as the architect and product manager of the WSO2 ESB, while he went onto start AdroitLogic in January 2010. Together we've written most of the Apache Synapse ESB in the past, and been the release leads of every release until now. Its great to be working with him back again, as I know him well as both a very technical person, and also as a good friend!

Having worked with multiple ESB's, I find the UltraESB to be comparatively easier to understand, configure and manage, with a much better and innovative design. I've just had to spend a couple of hours to learn the basics and get started using it, and looking at the code I find it very easy to follow the logic, coded with great unit test coverage and code quality as shown by Sonar at http://dev.adroitlogic.com:9090

Today I can look back and connect all the dots to see where life brought me. Its now a new chapter, as I close the one where I was a consultant. Although I enjoyed working independently, something within me wanted to get back into prime time product development. Like I said before, I have to love what I do, and designing and writing great software is what keeps me ticking! Being a part of the UltraESB will be a challenging yet fulfilling experience for me, and I look forward to making it an even better product than it is now!

Scala, is it comparable to Ruby?

2011-04-01T09:48:00.004+05:30

I've been looking at Scala for quite some time now, and Ruby was my language of interest when I was at University. Disclaimer : of course my knowledge on both above with compared the Java know-how is nill, but I love to learn programming languages and compilers. That's my area of interest too.

Being said that I fund some interesting debates on Scala vs Ruby. First of which is very interesting and famous The great Twitter Ruby vs Scala ~~war~~ debate and the next interesting discussion on this subject is Ruby versus Scala.

Anyway, my view on these discussions is pretty different. I think this is comparing Apples to Oranges, because AFAIK Scala is a strongly typed language while Ruby is a dynamic language. Both have there own advantages on the space that they have targeted the language to land. Most of the people take Ruby on Rails to be Ruby which is very annoying, as Ruby is far more than Rails.

Though I wanted to write about Scala, I am getting dragged to Ruby :-) as I think I still know Ruby a little more than Scala. Scala looks to be a good stable language for concurrent/parallel programming. Further to that even though Scala has been positioned as a mix of Object Orientation and Functional programming, from what I have learned so far it looks to be biased more towards functional programming.

As a summery, I think Scala is a great language so does Ruby if you are trying to compare those 2 I think you haven't isolated the layers of your application correctly, as Ruby targets a different programming paradigm than Scala. Still learning Scala and hope to do some magic stuff with it soon. :-)

On a side note, after learning these odd languages I am wondering why don't we come up with a standard language for integration, (is that SCA, I don't think so) I am now dreaming to come up with a language for integration.... just a hint for what I will be doing in the future.

A new beginning

2011-03-09T19:04:00.007+05:30

As of yesterday, the 8th of March 2011, I've left WSO2 after four and a half years. I joined WSO2 as a Software Engineer in September 2006, immediately after passing out from the University of Moratuwa, Sri Lanka. I was an Architect and Product Manager at WSO2, and lead the WSO2 ESB through many successful releases and client engagements.

I was never a person who was easily satisfied :-) So I always ensured that there was a target for me to achieve, and did whatever it took to realize it!

My childhood aim was to become an engineer, and this was achieved through a scholarship to enter the University of Moratuwa. Then my aim was to specialize in Computer Science, and I graduated with first class honors, to join WSO2. Then my dream was to become a Software Architect, and I achieved it in just 3 1/2 years.

Leaving WSO2

When I joined WSO2, my resume stated my objective was as follows: "My ambition is to be a useful software developer/designer for the community and to the company that I work for and be satisfied with the work I do". I wanted to realize this fully to the last word and letter!

Ralph Waldo Emerson said "To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment". Steve Jobs again stressed this in "Connecting the dots". I've gotta love what I do, and designing and writing great software is what keeps me ticking!

From now on, I'll be a consultant on enterprise systems integration specializing in the use of ESBs, and increase my involvement in Apache Software Foundation projects; now as one of its elected members. I'll also work with other large enterprises and possibly government institutions as a consultant.

As life moves on, its just the end of one chapter, and the beginning of another. But whichever chapter it maybe, I'll be designing and writing great software, and always be enjoying what I do!

NBQSA 2010 - Overall Gold award goes to WSO2 ESB

2010-10-03T21:00:00.010+05:30

NBQSA (National Best Quality Software Award) is an annual award ceremony held in Sri Lanka to evaluate and award the Software developedin the country. This is hosted by BCSSL (British Computer Society - Sri Lanka)

WSO2 marketing team decided to submit 3 of our products to this award evaluation, it was just few days we had to prepare for this presentation. I initially objected to submitting WSO2 ESB (the product that I am responsible of in WSO2) for this so quickly, as my intention was to win the first price if we are to submit. Kushlani from our marketing team together with Asanka has been driving this and motivated us a lot to submit for this.

Well, we spent few hours and Miyuru, Kasun and few others get together with me and prepared a plan to execute with a presentation script and demonstration. Miyuru did the first round

presentation and we got through to the second round easily. Hiranya took it over and we delivered the second presentation, to which we got a very good response from the judges.

Then, we were waiting to see the results and we had to app

arently wait till, day before yesterday (1st of October 2010) for that.

From WSo2 8 of us got invited and we all went on time with a lot of enthusiasm as all 3 of our products were on the wining cycle. The award ceremony got started and the first

to get an award from the 3 products was the WSO2 Gadget Server which got the Silver award under the RnD software category.

Then I was so waiting till the Infrastructure and Tools category to be awarded since both the WSO2 Data Services and WSO2 ESB was on that category.

They had only 2 awards on that category and one Bronze and a Gold. When it is announced that WSO2 DS as the bronze award I knew that ESB is getting the Gold award. I was not that excited, to be frank, I sort of knew that we are going to get it on our category :-) I was expecting the overall gold award. ;-)

Then they came to announcing the final overall awards, before which they have given out some special awards, but ESB was no where on those special awards. I was waitin

g and waiting and waiting... so does all of us from WSO2.

Finally they have announced the Bronze and Silver awards and those are the folks who won some special awards and I was 90% sure about my expectation now. And they finally announced WSo2 ESB as the Overall Gold winner at NBQSA 2010. I was so excited to accept the best award on that ceremony as the product manager of WSO2 ESB. I got down from the stage holding the most valuable award of the nite as the most proud man on that nite, though I must say that this price is for the whole WSO2 team including the past members of our team.

All of us who participated for the event from Left, Samisa, Asanka, Kushlani, Miyuru (holding the Gadget Server silver award), Me (holding the overall gold for ESB), Hiranya (holding the ESB Gold award on Infrastructure and Tools category), Sumedha (holding Data Service Server bronze award) and Azeez.

Now we are about to head towards APICTA in next week at Malaysia, Kuala Lumpur. Will update on that as well. :-)

First time experience of an Earthquake

2010-07-02T00:44:00.002+05:30

So, I came into Mexico, to be specific to Mexico City, the Sheraton Maria Isabella Hotel and Towers for a customer engagement on behalf of my Office, WSO2 Inc. I had another friend of mine (Amila) with me.

Because of the customer work we are more or less alive on the whole night, to get the required scenarios working. My friend went into sleep on this specific day, which is 30th of June 2010 at around mid night, but I was still working. My laptop was on my bed and suddenly I felt my laptop going away from me and coming back to me :-) With that I also felt like some God is shivering the multi story building, on which we were on the 6th floor.

I stood up and still the building was like a pendulum. I realized this is a Earthquake apparently it is of 6.2 magnitude. :-( After about 5 minutes the building settled, and later I found that, that building is designed to move like that in an earthquake.

Next generation of ESB - WSO2 ESB 3.0.0 Released

2010-05-03T23:42:00.001+05:30

The WSO2 Enterprise Service Bus (ESB) 3.0.0 Released!

The WSO2 ESB team is pleased to announce the release of version 3.0.0 of the Open Source Enterprise Service Bus (ESB).

WSO2 ESB is a fast, lightweight and user friendly open source Enterprise Service Bus (ESB) distributed under the Apache Software License v2.0. WSO2 ESB allows system administrators and developers to easily configure message routing, intermediation, transformation, logging, task scheduling, fail over routing and load balancing. It also supports transport switching, eventing, rule based mediation and priority based mediation for advanced integration requirements. The ESB runtime is designed to be completely asynchronous, non-blocking and streaming based on the Apache Synapse mediation engine.

WSO2 ESB 3.0.0 is developed on top of the revolutionary WSO2 Carbon platform (Middleware a' la carte), an OSGi based framework that provides seamless modularity to your SOA via componentization. This release also contains many new features and a range of optional components (add-ons) that can be installed to customize the behavior of the ESB. Further, any existing features of the ESB which are not required to your environment can be easily removed using the underlying provisioning framework of Carbon. In brief, WSO2 ESB can be fully customized and tailored to meet your exact SOA needs.

You can download this distribution from http://wso2.org/downloads/esb and give it a try.

How to Run

Extract the downloaded zip
Go to the bin directory in the extracted folder
Run the wso2server.sh or wso2server.bat as appropriate
Point your browser to the URL https://localhost:9443/carbon
Use "admin", "admin" as the username and password to login as an admin and create a user account
Assign the required permissions to the user through a role
If you need to start the OSGi console with the server use the property -DosgiConsole when starting the server. The INSTALL.txt file found on the installation directory will give you a comprehensive set of options and properties that can be passed into the startup script
Sample configurations can be started by the wso2esb-samples script passing the sample number with the -sn option (Please have a look at the samples guide for more information, on running samples)

WSO2 Steps into Cloud

2009-11-19T20:11:00.010+05:30

This week, WSO2 has announced there cloud offerings introducing the Cloud SOA platform. With this we (WSO2) enters into cloud computing...

Cloud platform that WSo2 provides mainly consists of three variations; which are;

Cloud Virtual Machines
Cloud Connectors
Cloud Services

First of all lets take a look at the Cloud Virtual Machines. They are basically hardened virtual machines pre configured to be run on the cloud with auto scaling to fit into your load. This will be very cost effective since you pay it as you go, but still providing the production support insurance.

You may try out those as Amazon EC2 images or may be you can run them on your own as VMware images or Linux KVM images.

You should have been at least worring once in your life being not able to provide a third party access the service running on your laptop, since you are under a NAT. Well the second solution that WSO2 provides addresses this issue with a Cloud Connector which is the Cloud Services Gateway which enables you to just expose the service running on WSAS or ESB instance on your personal desktop/laptop connected to the internet, even though the third party cannot access your machine.

Another Cloud Connector will accelarate the security processing by delegating that bit to a virtual machine optimized to perform security which is called the Cloud Service Accelarator.

The final option (for the time being) is the Cloud Services, you may have heard the term "as a Service" much more frequently these days. So WSO2 exposes its Governance solution as a service naming it GaaS (Governance as a Service).

It will be very interesting for you to try out GaaS online.

We are not done yet, stay tuned for the next step towards the cloud; As a hint I would say IdaaS is coming soon. Guess what it is.... :-)

All the above will form the WSO2 Cloud Middleware, whcih will be the onestop shop for all your cloud requirements... Stay tuned...

Want to know more and more, yeah! join Paul Fremantle for the free Webinar on Cloud and SOA: A revolution for the enterprise on Tuesday, November 24, 2009 from 09:00 AM to 10:00 AM (PST).

WSO2 ESB 2.1.1 is Released!

2009-10-12T07:03:00.001+05:30

So this time it is a bug fix release but with few enhancements as well called WSO2 ESB 2.1.1;

The WSO2 Enterprise Service Bus (ESB) 2.1.1 Released!

The WSO2 ESB team is pleased to announce the release of version 2.1.1 of the Open Source Enterprise Service Bus (ESB). This is an enhanced and improved release of the WSO2 ESB 2.1.0 which went out on July 2009.

WSO2 ESB is a lightweight and easy-to-use Open Source Enterprise Service Bus (ESB) available under the Apache Software License v2.0. WSO2 ESB allows administrators to simply and easily configure message routing, intermediation, transformation, logging, task scheduling, load balancing, failover routing, event brokering, etc.. The runtime has been designed to be completely asynchronous, non-blocking and streaming based on the Apache Synapse core.

WSO2 ESB 2.1.1 is developed on top of the revolutionary Carbon platform (Middleware a' la carte), and is based on the OSGi framework to achieve the better modularity for your SOA architecture. This also contains a lots of new features and many other optional components to customize the behavior of the server. Further, if you do not want any of the built in features, you can uninstall those features without any trouble. In other words, this ESB can be customized to your SOA needs.

You can download this distribution from http://wso2.org/downloads/esb and give it a try.

How to Run

Extract the downloaded zip
Go to the bin directory in the extracted folder
Run the wso2server.sh or wso2server.bat as appropriate
Point your browser to the URL https://localhost:9443/carbon
Use "admin", "admin" as the username and password to login as an admin and create a user account
Assign the required permissions to the user through a role
If you need to start the OSGi console with the server use the property -DosgiConsole when starting the server. The INSTALL.txt file found on the installation directory will give you a comprehensive set of options and properties that can be passed into the startup script
Samples configurations can be started by the wso2esb-samples script passing the sample number with the -sn option, please have a look at the samples guide for more information, on running samples

Also I must say that this webinar has been reported as a record braking webinar for WSO2 with the huge number of attendies.

I will be doing a series of webinars which will demonstrate the functionalities of the ESB starting soon...

Enterprise Integration Made Easy with the WSO2 ESB

2009-08-24T20:39:00.003+05:30

So this is about a webinar that I am planning to do on 1st of September 2009 about the WSO2 ESB 2.1 release.

"Enterprise integration can be a real drag for developers. Even though the advent of SOA has made the need for hard-coded integration between each application obsolete, it can be frustrating and time-consuming to get your middleware tools set up to build, mediate and connect services."

You can read the full story at WSO2.org

It is free, and has a limited number of seats ;-) so be hurry, Register Now.

I will be covering the WSO2 ESB focusing on the;

An overview of the new OSGi-based architecture
The provisioning model to seamlessly add or remove components and custom features to your ESB deployment
Better mediation and routing with the new business rules support, powered by Drools
How the WSO2 ESB automatically protects your integration development efforts by storing your configuration in a built-in registry
Additional enhancements to performance, eventing support, scheduled tasks and REST support
Streaming and non blocking HTTP transport and other supported transports, interfaces and protocols

Once again be hurry!

[WSO2-ESB-FAQ-001] Per-service logs in WSO2 ESB

2009-08-05T19:51:00.006+05:30

Now, that WSO2 ESB is getting the attraction of the community I thought of sharing a piece of useful information through my Blog. I thought I am going to blog about the features of the WSO2 ESB one by one and at the next release we will be including them all in the ESB documentation as FAQ's :-)

So first of all lets focus on the requirement, my requirement is to configure the logs of a particular service (to be more specific a proxy service) to be logged into a given log file. The advantage of having per-service log files is that it is very easy to analyse/monitor what went wrong in this particular proxy service by looking at the service log. Enabling this feature will not terminate the wso2-esb.log file being keeping the logs about this service, the complete log is a complete log and will contain every log statement including the service logs that you have configured to be logged into a different log file. In other words the service log is an additional log file which will contain a copy of the logs to that particular service.

Then, how can you configure this in the WSO2 ESB. So, lets assume that we are referring to the sample 150 of the WSO2 ESB, which has a proxy service named StockQuoteProxy. Now we need to configure log4j to log the service specific logs to a file called stock-quote-proxy-service.log in the logs directory of the ESB installation directory. Open up the log4j.properties file found at the lib directory of the WSO2 ESB installation directory using your favourite text editor and add the following section to the end of the file starting in a new line;

 log4j.category.SERVICE_LOGGER.StockQuoteProxy=DEBUG, SQ_PROXY_APPENDER
log4j.additivity.SERVICE_LOGGER.StockQuoteProxy=false
log4j.appender.SQ_PROXY_APPENDER=org.apache.log4j.DailyRollingFileAppender
log4j.appender.SQ_PROXY_APPENDER.File=logs/stock-quote-proxy-service.log
log4j.appender.SQ_PROXY_APPENDER.datePattern='.'yyyy-MM-dd-HH-mm
log4j.appender.SQ_PROXY_APPENDER.layout=org.apache.log4j.PatternLayout
log4j.appender.SQ_PROXY_APPENDER.layout.ConversionPattern=%d{ISO8601} [%X{ip}-%X{host}] [%t] %5p %c{1} %m%n

Well, save the file and you are done with the configuration, and now it is time to try it out. By default the sample 150 configuration doesn't do any logging at run time. So go ahead and configure the proxy service in-sequence to contain a log mediator to log the message at "Full" log level.

Execute the sample client after starting the ESB with the sample 150;

  $ESB_HOME/bin/wso2esb-samples.sh -sn 150

and the sample axis2 server with SimpleStockQuote service deployed on it as per stated in the sample documentation.

Inspect the logs directory of the ESB installation directory to see the stock-quote-proxy-service.log file, further to demonstrate the log file rotation I have configured this particular logger to rotate the file in each minute when ever there is a log going into the service log, so if you execute the sample client once again after 1 minute you will be able to see the service log file rotation as well.

Sri Lanka wins the ODI series over Pakistan

2009-08-03T19:27:00.007+05:30

Wow, what a knock it was from Mahela Jayawardhana and Upul Tharanga of 202 record braking opening partnership, which brings Sri Lanka the first ODI series win over Pakistan at Home.

When Pakistan hit 288 I thought "its OK we will be having two other matches at Colombo to mark the series win", coz I never thought we (Sri Lanka) will win the match at Dambulla even without Sanath Jayasuriya. Well, I was completely wrong but after watching 12 overs of Sri Lankan batting I knew that we are going to win. I had much stuff tobe done, but just set for watching a couple of overs of yet another Sokian batting :-), but I get off from my seat even after the awards presentation.

See the Full score card it was marvolles. It was all Mahela's game today Congratulations to him!

Everybody was talking about Mahela who had become the man of the match, well he deserves that, but if not that decision of Ashoka De Silva to wrongly judge Upul Tharanga to be victimed to a LBW, Tharanga would have been going for a century for sure as well.

Apart from that I saw a fabulus catch from Mathews, he is a such a talented cricketer and a great finding into the Sri Lankan team, he can ball very well, his batting is quite out standing and nothign to talk about his fielding, I just got to remember Roshan Mahanama for a second when I saw Mathews taking that in flight return catch.

Finally, this man has something to talk about in every match, so proving that he has his portion to talk about him in this match as well. Congratulations to Muralli for the hurdle of 600 ODI wickets.

I am delighted to see the T/20, Pakistan is the world cup holder ;-), lets wait and see.

Bill Gates on Sri Lanka

2009-07-19T20:07:00.006+05:30

I just got a notification from Google Alerts, (since I had an alert set up for WSO2) on Ajith's blog entry from where I saw this video.

It is amazing that how the world recognizes Sri Lanka on the worlds IT industry... I think considerable amount of acknowledgement should go to Dr. Sanjiva Weerawarana who helps the talented Sri Lankans to show off there abilities on the global IT industry. I am fortunate enough to be guided from him.

Apart form that I should also mention about the University Of Moratuwa, Sri Lanka, which constructs most of these talented Sri Lankan stars from the scratch; well to be more specific the Department of Computer Science & Engineering. I am proud to be part of that as well. For example, when I was entering to the university to do my B.Sc. Engineering degree, I had just only seen a computer and touched it for several times.. but it at least took me 30-40 seconds to type in my name "Ruwan Linton" :-), I am proud to be a well instrumented Software Engineer after 4 years of studies, I know this story is true for most of the people who came to the university from country side, at least on those days. So, a huge thank to CSE - UOM as well.

Congratulations to Sri Lanka... and our guys.

Rule based mediaiton enabled in the Open Source ESB

2009-07-15T23:19:00.003+05:30

Now you should already be aware of the new release of the open source ESB, which is the 2.1.0 version of the WSO2 ESB.

It is a much matured release, but it is not just the maturity and stability which brings to you by this release but a few very important new features... Top on my list is the Rule based mediation and this post is about that.

First of all lets look at, what is Rules, Rules Engine and what is the importance of Rules in to the message mediation in SOA?

Rules is a functional construct which is used to match the decision making from the technical aspect to the business aspect of it. Basically you need to provide in a set of name value pairs as facts and then you need to specify a set of rules to the Rules Engine, and the engine will process these facts according to the specified rules. When it comes to SOA, it is vital to have this sort of a configurable processing of the messages according to a set of rules over the messages.

This model better fits into an ESB rather than a service hosting environment, this doesn't mean that WSO2 will not going to make it to Rule based services (or may be Rules as a service) but it has much value at the mediation layer, especially with the power of Complex Event Processing with Rules. WSO2 ESB uses the Drools as the Rule implementation which enables you to add CEP to the ESB very easily because the latest release of Drools has the CEP capabilities as well.

The other main advantage of using the WSO2 ESB over any otehr ESB is the comprehensive set of samples which helps you get off the ground quickly. Same is true for Rules as well, we have 6 samples explaining the different behaviors of the Rule based mediations. If you haven't yet tried the open source ESB, now it is the time to get started with it by downloading it or never look at it :-).

Security in SOA

2009-07-13T22:56:00.003+05:30

Security is a hard to understand subject for most of the people, yet again just think about how complex it is when it is applied to Service Oriented Architecture. I also had a time where I don't even look at such scenarios... but just have a look at this. Kudos to Prabath and the WSO2 Security team, it is just simple and explained in a story styled presentation.

Implementing Master Data Management Patterns

2009-07-12T23:22:00.002+05:30

Master data is important for any business. Managing master data is critical as businesses makes decisions based on them. It is still valid for systems developed following the service oriented architecture styles as well. This article describes how to map MDM with SOA deployments with details of how to architecture. The WSO2 SOA platform is shipped with features required for such an implementation.

This article by Asanka Abesinghe explains how you can implement the MDM patterns with the WSO2 SOA platform.

WSO2 ESB - The Open Source ESB 2.1.0 is Released

2009-07-10T22:48:00.004+05:30

It is done! and is out there in GA for you to try at the product downloads page.

This release is a much more stabilized release, with all the OSGi maturity and the component architecture being solidly applied to the product it self.

You could find the Release Note here to get an idea of the release.

If I list the top 5 features of this release;

Rules support with Drools
Fully AJAX based Sequence Editor
Fine grained authorization via an Entitlement mediator
WS-Reliable Messaging 1.1 support
Full REST support

Well, there are many more you should give it a try for sure.

One other thing is that, we have improved a lot on the documentation... you could get a feeling of the improvement if you have seen this documentation earlier, even if not you may realize that this documentation is comprehensive.

One blame that the industry is raising against open source products are the lack of documentation and we have tried our very best to address that in this release. Don't worry it is still open source and released under the Apache Software License v2.0

This ESB release goes with 3 other twin WSO2 products which are G-Reg the Governance Registry, WSAS the Web Services Application Server and IS the Identity Server which you will find interesting to get your hands into.

WSO2 ESB 2.1 is just about to meet the enterprise

2009-06-20T11:31:00.004+05:30

So, first of all... I was not being able to even write a few blogs in the past few months because we are trying very hard to give the birth to the new child of the WSO2 ESB family which is its 2.1 version.

Now it is available for you to try out in the form of beta1. It is interesting that how WSO2 defines the releases.

Milestone releases - Each and every milestone will add a set of new features, but we try our best to limit the new features in a given milestone to a absolute minimum (like only one) to prevent the issue of finding which causes the regression X
Alpha release - All features are complete, but there is no guarantee about the stability
Beta releases - All Level 1 issues are fixed and the release is guaranteed to be stable from the development perspective
Release Candidates - All Level 1 and Level 2 issues are fixed and the release is ready to go for the GA
General Availability - Ready for the Production

So, currently WSO2 ESB and its all twins including WSAS, G-Reg and IS are on the Beta phase waiting for the birth to the enterprise...

You could try out this and give us the feed back on any sort of an improvement or issues in the CARBON JIRA

Please note that how you run the samples in the WSO2 ESB has been changed and now you are provided with a new script to run samples... which just do some preparation for the samples before runing the ESB. You need to use the wso2esb-samples.sh with the -sn option.

Even though the release is available as beta for the public internally the development is just about to reach the RC phase with no Level1 and Level2 issues. You could see this with the CARBON JIRA where the active development on the release is happening. I need to sync up the ESB JIRA coz most of the issues reported there are already fixed..

Waiting for your feed back for the birth...

OSGi as Framework for Building a Product Line

2009-04-04T11:00:00.002+05:30

One more talk from the ApacheCon Europe 2009! on "Building a Product Line using an OSGi framework" of course using WSO2 Carbon.

Some of the challenges include the proper sizing and architecture of OSGi bundles, managing dynamic bundle dependencies, dealing with OSGi implementation incompatibilities and scalability. However, the net result has been tremendously successful in creating a platform that allowed extend/replace functionality almost trivially.

Scalability & Availability with Synapse

2009-04-04T10:49:00.002+05:30

I have done a talk on ApacheCon Europe 2009 in Amsterdam on "Achieving Scalability and High Availability using Apache Synapse", and this is all about that talk.

This requires a cluster of services to be available and Synapse will balance the load and fail over route the messages among the cluster of services to provide scalability and availability. Apache Synapse is designed to be a simple, lightweight and high performance Enterprise Service Bus (ESB). Since it is based on a small asynchronous core, it can handle 2500 concurrent connections on a standard server hardware. The Synapse engine is configured with a simple XML format and comes with a set of ready-to-use transports on which it can be used as a load balancer and a fail over router. Synapse supports static and dynamic load balancing, static load balancing can be used when you have a set of known hosts in the cluster where as dynamic load balancing could be used for an environment where the nodes on the service cluster is dynamic for example when auto scaling of the service cluster is active. In the case of dynamic load balancing the load balance endpoint gets the list of nodes which provides this service from the underlying Group Communication Framework of the cluster. Apache Synapse can be used for general mediation tasks while providing the scalability and availability to a set of services as well. You may use Synapse to log the messages coming into your network or to throttle the messages to your services

Terror attack on Sri Lankan National Cricket team in Pakistan

2009-03-03T22:53:00.003+05:30

Pakistan's status as an international sporting venue has come under doubt after masked terrorists attacked the team bus carrying Sri Lanka's cricketers to the Gaddafi stadium in Lahore on Tuesday morning. Five cricketers, including Mahela Jayawardene, the captain, and Kumar Sangakkara, his deputy, received minor injuries. Ajantha Mendis, Thilan Samaraweera and Tharanga Paravitarana were also injured in the attack which killed six security men and two civilians.

The ongoing Lahore Test has been called off and the tour cancelled. Sri Lanka's cricketers were evacuated from Gaddafi stadium and taken to a nearby airbase from where they are to fly back to Colombo.

WSO2 ESB 2.0.1 Released !!

2009-02-27T20:21:00.004+05:30

After the WSO2 ESB 2.0 release, the wso2 team has figured out some very minor issues in the registry and some of the ESB user interface issues, which resulted in the 2.0.1 bug fix release of the WSO2 ESB.

You can download this distribution from http://wso2.org/downloads/esb and give it a try.

The release note is available at here.

WSO2 ESB is a lightweight and easy-to-use Open Source Enterprise Service Bus (ESB) available under the Apache Software License v2.0. WSO2 ESB allows administrators to simply and easily configure message routing, intermediation, transformation, logging, task scheduling, etc.. The runtime has been designed to be completely asynchronous, non-blocking and streaming based on the Apache Synapse core.

We are planning to release a set of feature packs soon, so that you could experience the power of carbon by adding features from another server to the ESB, like service hosting and BPEL. We have started this process of releasing the feature packs with the service mediation feature pack. Check out the Carbon page and stay tuned !!

What is Data Services?

2009-02-27T07:08:00.002+05:30

Data Services is becoming a key part of SOA, because it enables the data collected by legacy applications (well, it is the database of the legacy application to be more precious) to be exposed as a web service.

WSO2 Data Services solution provides the ability to expose your database as a service, over what ever the way you want by allowing you to expose database queries as web service operations.

This flash demonstration shows you the abilities of wso2 data services solution. While the data services solution exposes the database as a service it also gives the ability to add various QoS to the just exposed service.

Most interestingly this solution is going to be released very soon as a child of the Carbon middleware family.

Adding Mediation to WSO2 WSAS

2009-02-25T23:14:00.002+05:30

Have you ever thought of integrating two products into one, at least two WSO2 products?

This article explains how to add mediation to a WSO2 WSAS instance. This will allow you to use the mediation functionalities of the WSO2 ESB for the services deployed on WSAS, without having yet another ESB instance to intercept the messaging between the service invoker and the service host.

Read the full story of how to add mediation to WSO2 WSAS, or you could watch the screen cast which shows exactly the same.

Mediation on WSAS services will be different from ESB layer mediation, in which case there is a third party who is doing the mediation between the service invoker and the service host. The mediation capability that can be added to WSAS brings the mediation to be bundled into the service host. While both these approaches has its own pros and cons, they should be used carefully by analyzing your requirement.

WSO2 Carbon Core Released !!

2009-02-25T22:05:00.005+05:30

WSO2 has released the whole SOA middleware stack on top of the modular, revolutionary carbon platform to standardize the products including the WSO2 ESB, WSO2 WSAS, WSO2 Registry and WSO2 BPS. One other child of this family is on his way and will pop up soon which is the WSO2 DS Solution.

This blog by Samisa explains all about carbon. So, after all this jargon on OSGi, modularity, agility, extensibility and Carbon, you might be wondering whether this is actually true or is this just a marketing point that WSO2 is using. The carbon core is the answer to your questions and now we have released the carbon core on top of which all most all our products have been built.

Proving the modularity of the Carbon framework and the WSO2 product stack you could build any of the WSO2 products starting from the Carbon core, and this core is the least common denominator of the WSO2 products. This could be better explained in the following diagram....

WSO2 releases a set of feature packs which are a collection of interrelated components that adds a particular functionality into this carbon core. Therefore, either you can add components by your self getting them from the WSO2 maven2 repository or you could download these feature packs to install features onto WSO2 Carbon Core.

Please note that we will be releasing more feature packs within another 2-3 days and for the moment it contains the service mediation feature pack.

Stay tuned for how you can customize your carbon based products ....

WSO2 Mashup Server 1.5.2 - Released !!

2009-02-21T23:58:00.002+05:30

WSO2 Mashup server is not yet carbonized but we have started the Carbonization ... So before we dig into the carbonized improved version of the Mashup server 2.0 the team thought of doing a bug fix release to serve the users who are using the 1.x versions of the Mashup server.

Keith explains all about this release in his blog..... and it will be more than important for you all to upgrade to the latest version if you are already using it.

Await for the WSO2 Carbon based Mashup server, probably in May .... and ig you need to read more about the mashup server 1.5.2 please follow the release note.

Eventing using Apache Synapse and WSO2 ESB

2009-02-19T15:34:00.004+05:30

This is the second of the series of eventing articles by Asanka Abesinghe an architect of WSO2. If you haven't read the firs one you may read it first.

WSO2 ESB 2.0 adds eventing capabilities to the ESB, with support for subscription management and features related to event brokering. Eventing is built based on the WS-Eventing specification (August 2004). Default distribution comes with two subscription managers, topic based in-memory and topic based remote registry, where the user has freedom to write a custom subscription manager implementation and plug that with the ESB.

Eventing implementation provides powerful mediation capability for events. Based on the event brokering architecture of the WSO2 ESB, any existing mediation can configure and send messages through relevant mediators before dispatching these to endpoint(s). A new mediator called the 'eventPublisher' is added to the mediation library in order to facilitate event brokering.

Read the full article....

The above specified features lets you implement an operational model for ESB based on the Event Driven Architecture (EDA) which come very handy in the enterprises integration.

Need for New Global Conventions

2009-02-18T22:27:00.002+05:30

Dr. Thrishantha Nanayakkara on Need for New Global Conventions,

On Feb. 9, an LTTE suicide bomber killed herself inside a crowded transit camp maintained by the government for displaced Tamil civilians in northern Sri Lanka. She killed and injured scores of Tamil men, women, and children awaiting transport to safer areas. A day later, the LTTE shot and killed 19 civilians as they attempted to cross over to government held areas. The incident was not widely reported in international media, perhaps due to its low political appeal. However, it is absolutely imperative that we resolve—as a global community—that no rebel group or government be allowed to commit such crimes against humanity again.

Story of Carbon and a Smart car

2009-02-18T07:12:00.003+05:30

Samisa blogged about Carbon
to start with this smart car model
in the Give up your SUV, and SUV like Middleware post,

followed by Chinthana explaining this concept
about Carbon comparing it to a Hummer
in his post on Drive as a Hummer, save as a Prius

and finally again Samisa
on aggregating these two posts to explain what he meant exactly
with the post A Hummer, a Prius or a smart car.

I think what all these tries to explain is to give up on the high cost middleware at this economic situation and use these cost effective middleware with the same set of features, yet again with more performance and more modularity.

Take a ride on it ..... !!

Carbon feature packs are started to flow out

2009-02-10T20:22:00.005+05:30

First of the series of Carbon feature packs is just launched today which is called the wso2-mediation-feature-2.0.zip. These feature packs contain a unit of functionality or a set of functionalities which can be used to easily customize the behavior of a carbon based product.

In other words, these packs contains a set of components or OSGi bundles and optionally can contain configurations specific to that particular feature. You could get these packs and install on your existing carbon based products to extend the functionality of your product.

This particular mediation feature pack adds the ability of mediation on the service host side to WSO2 WSAS, and is provided as a feature pack of WSO2 ESB.

As shown in this image you should be able to see the user interface corresponding to the added features in the administration console.

In the same line, we will be releasing the service hosting feature component, business process feature component and data services feature component together with the advanced registry feature components.

Stay tuned for more information on these feature packs, and this again illustrates the power of Carbon.

ESB-2.0 Press Release is out

2009-02-09T21:41:00.002+05:30

WSO2, the open source SOA company, today released version 2.0 of the WSO2 Enterprise Service Bus (ESB). The completely re-architected open source WSO2 ESB 2.0 is now based on WSO2 Carbon, the industry’s first fully componentized service-oriented architecture (SOA) framework.

The modular WSO2 ESB 2.0 provides unprecedented flexibility for managing service-oriented connections in an enterprise. Because it is based on the WSO2 Carbon system, developers can now plug in extra components to handle tasks, such as service hosting, business process management, and SOA governance without disrupting existing flows and configuration. The ability to customize the behavior of the ESB with a plug-and-play simplicity eliminates the typical cost and complexity of integration.

Read more.

With this ESB release WSO2 has also released three other products including the platform.

WSO2 Carbon [The SOA platform - Middleware a' la carte]
WSO2 WSAS [Web services application server]
WSO2 Registry [Governance to your SOA]
WSO2 BPS [Business process server]

Componentized SOA

2009-02-07T08:59:00.003+05:30

A success story of componentizing the SOA..

"What we’ve done is basically broken down the implementation of the server platform that we had into a collection of components based on OSGi," said Sanjiva Weerawarana, CEO of WSO2. Without this type of componentization capabilities, users can end up with too much overhead, security issues, and complications in upgrading, Weerawarana said.

You could read more on this at InfoWorld.

Being said all that, WSO2 ESB-2.0 is part of this revolutionary framework, which we have improved in many ways from its previous version.

WSO2 ESB-2.0 GA is just out there !!

2009-02-06T23:30:00.000+05:30

It was a great experience and this is my first release as the product manager of the WSO2 ESB which will be based on the most agile middleware platform - Middleware a' la carte - CARBON.

Visit the WSO2 ESB project page to see more information on this great invention, or you could directly go to the download page. This time we are releasing the documentation as a separate bundle and hence the samples guide and all the relevant documentation will be available on the documentation artifact.

Release note will give you a better understanding on the WSO2 ESB 2.0 while you could read more about it on the online documentation.

--- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- ---

WSO2 ESB is a lightweight and easy-to-use Open Source Enterprise Service Bus (ESB) available under the Apache Software License v2.0. WSO2 ESB allows administrators to simply and easily configure message routing, intermediation, transformation, logging, task scheduling, etc.. The runtime has been designed to be completely asynchronous, non-blocking and streaming based on the Apache Synapse core.

WSO2 ESB 2.0 is developed on top of the revolutionary Carbon platform (Middleware a' la carte), and is based on the OSGi framework to achieve the better modularity for your SOA architecture. This also contains a lots of new features and many other optional components to customize the behavior of the server. Further, if you do not want any of the built in features, you can uninstall those features without any trouble. In other words, this ESB can be customized to your SOA needs.

--- --- --- --- --- --- --- --- --- --- --- --- --- --- --- --- ---

WSO2 also releases a set of other SOA related products making the WSO2 platform completely an SOA stack for the industry. WSO2 WSAS is a web services application server, WSO2 Registry is the registry solution which also provides SOA governance and the WSO2 BPS which is the business process server to manage BPEL interactions. You may give them all a try.

Most importantly you could now add features from each of these products to WSO2 ESB just by adding the relevant components. In other words, all the features in this product stack are developed as feature components which are self contained so that by adding those component to any carbon server you could get that functionality on that particular server.

This lets you to “Adapt the middleware to your architecture, and not your architecture to the middleware”, which will be one of the turning points of the future of middleware applications.

ESB 2.0 is yet to go off but we are almost there

2009-01-12T21:33:00.002+05:30

Today the WSO2 ESB team released the final beta of the WSO2 ESB 2.0 and it is the 3rd beta, which can be downloaded from the http://wso2.org/downloads/esb

Stay tuned for the final release in the end of January or may be in the first week of February.

Apache OFBiz Development

2008-12-28T07:42:00.004+05:30

"Apache Open For Business or OFBiz as it is more commonly known, is an open source framework designed to facilitate the building of Enterprise Resource Planning (ERP) software. ERP is a general name for any system which attempts to integrate all business processes and underlying data into one single system. Indeed the OFBiz framework not only facilitates the building of your own custom software, but also comes packaged with many tools you would expect from an ERP system, and much more. The extent to which you wish to use these applications is entirely up to you and the needs of your business. Some businesses choose to use some or all of these components virtually straight out of the box. Others may spend time and money customizing these components or building new ones to suit their own needs and their own unique business processes.

ESB 2.0 beta1 released on OSGi

2008-12-12T22:42:00.004+05:30

The WSO2 ESB team is pleased to announce the release of version
2.0-beta1 of the Open Source Enterprise Service Bus (ESB).

WSO2 ESB is a lightweight and easy-to-use Open Source Enterprise Service
Bus (ESB) available under the Apache Software License
v2.0. WSO2 ESB allows administrators to simply and easily configure
message routing, intermediation, transformation, logging, task
scheduling, etc.. The runtime has been designed to be completely
asynchronous, non-blocking and streaming based on the Apache Synapse core.

WSO2 ESB 2.0-beta1 is developed on top of the revolutionary Carbon
platform (the WSO2 SOA platform), and is based on the OSGi framework to
achieve the better modularity for your SOA architecture. This also
contains a lots of new features and many other optional components to
customize the behavior of the server. All these components Further, if
you do not want any of the built in features, you can uninstall those
features without any trouble. In other words, this ESB can be customized
to your SOA needs.

You can download this distribution from [1] and give it a try.

How to Run

Extract the downloaded zip
Go to the bin directory in the extracted folder
Run the wso2server.sh or wso2server.bat as appropriate
Point you browser to the URL https://localhost:9443/carbon
Use "admin", "admin" as the username and password to login as an admin and create a user account.
Assign the required permissions to the user through a role
If you need to start the OSGi console with the server use the property -DosgiConsole when starting the server
Samples configurations can be specified by passing the property -Desb.sample=${SAMPLE_NUMBER}

New Features of this release includes;

Based on the OSGi based WSO2 Carbon platform. This is a unification of all Java based products from WSO2.
Enhanced fully internationalized User Interface
Separable frontend & backend - a single frontend server can be used to administer several cluster of backend servers
EDA support with WS-Eventing
Graphical user management, role management and user permissions

Carbon - The integration platform

2008-12-01T00:36:00.003+05:30

I didn't have time to even write up something in here... because of carbon, but it tends to get my attraction as a product.

WSO2 Carbon is going to be the next generation platform on which all our Java product stack is based on, including WSAS, ESB, Registry and the new sibling Process Container.

I was writing some little stuff about OSGi and of course these are related ;-) and the Carbon platform is based on OSGi and it provides a plugable architecture for our product stack. This blog of Samisa will explain most of it.

Even though ESB-2.0 is not yet complete on top of carbon, which is why I am so busy and still up at 12:45 AM, I feel it is going to be a nice product.

So, this once again verifies the vision of Paul, because he was the one who saw this upfront while most of us were not in agreement with him to change our products to OSGi. It is not perfect yet, but I am sure it is going to be... Otherwise there is no value of our sleepless nights.

Stay tuned for the ESB-2.0 based on Carbon, which allows you to add more functionality like service hosting, BPEL and many more seamlessly.

OSGi Bundle Start Levels

2008-10-21T21:04:00.003+05:30

We (WSO2) is in the process of making all most all its Java based products to be OSGi complaint. OSGi is designed to work on embedded devices where as now it is moving towards the Enterprises Application Servers and ESB's. This is because of the modularity and the version management of jar artifacts provided to Java libraries by the OSGi framework.

It is obvious that there are some things to be resolved from the OSGi framework side because it is not designed to support enterprise level massive applications yet. My personal view is that OSGi committee is working on the R5 release of the specification with considering all these enterprise adoption of the OSGi framework.

One of the issues that we have faced while developing our web services related middle ware stack is that the patching mechanism to which we have found a solution, which is a Clever Trick according to Peter Kriens

Coming back to Start Levels, OSGi provides the same concept of run levels in Unix and these start levels are managed by the StartLevel compendium service. Also, if you look at how to specify a start level ordering for a set of bundles to be installed at initiation time different implementations of the OSGi framework uses different mechanisms. I think this is a place where the R5 specification has to address before releasing it. If you look at Equinox it uses a properties file called config.ini where as Knopflerfish uses a file named init.xargs to specify the bundle start order which is basically the start levels.

Now, WSO2 is developing a stack of products which should be able to run on any OSGi implementation and also we have a requirement of being able to add new components at run time. If we are to use these vendor specific files to specify the start levels when we need to add a new component we will have to edit the relevant configuration file as well, which is going to be a user action and will be a pain to the user.

As a solution to this we came up with a Bundle Management Agent to listen for bundle INSTALLED event, and looks for a custom MANIFEST header named WSO2-Bundle-StartLevel inside the bundle MANIFEST. Then this agent will set the start level value to the bundle using the StartLevel service and mark it to start. Also if the framework start level is less than the just added bundle start level this agent increases the framework start level, in which case framework is going to start the bundles at there own start levels. At the initiation time this agent will assign start levels to all the INSTALLED bundles before increasing the framework start level to just above the highest start level (framework start level = highest start level of bundles + 1).

The above Clever Trick solves our problem partially, because the MANIFEST header is specific to WSO2. We cannot expect all the bundles to put the start level header which is custom to us. There fore I think providing this Start Level of a bundle has to be standardized by the next version of the OSGi specification.

WSO2 ESB fixes the Firefox3

2008-08-20T06:45:00.002+05:30

After all, we (WSO2 ESB Team) have decided to fix all the Firefox3 issues which were there with the 1.7 release in a minor bug fix release which is called 1.7.1.

WSO2 ESB 1.7.1 release is available for you to download and try out in Firefox3, while fixing the issues with Firefox3 we had to keep an eye on Firefox2 as well and it is guaranteed to work on both Firefox versions.

Backwards compatibility of browsers are very annoying because non of the two versions of browsers are backwards compatible. If we take Internet Explorer version 6 and 7 it is the same.

Being said that I must also say that, by fixing all the Firefox3 issues we were able to get the IE7 issues also fixed automatically. So the good news is that now both these browsers are compatible to some extent and lets hope they will try to keep the backwards compatibility from here onwards. :-)

BTW: I started to post on ESB-1.7.1 release and deviated to web browsers ;-) any way here is the release note of the WSO2 ESB 1.7.1 release if you are interested in.

Open Source Web Services with Ruby

2008-07-23T21:21:00.004+05:30

Ruby is an interesting dynamic programing language which is considered as a scripting language. Well, I don't think it is fair enough to categorize it as just a Scripting Language, but it should be considered as a fully fledged programing language.

Proving that WSF/Ruby adds the capability of doing Web Services with Ruby. WSF/Ruby is released under Open Source Apache Software License 2.0 and WSF/Ruby team at WSO2 has just released its 1.1.0 version today (23rd July 2008). WSF/Ruby enables you to consume/provide Web Services both with REST and with the power of WS-* stack including WS-Reliable Messaging, WS-Security, WS-Addressing and MTOM Attachments with Ruby.

Key Features of the WSF/Ruby framework includes;

Client API to consume Web services
Service API to provide Web services
Attachments with MTOM
WS-Addressing
WS-Security
WS-Reliable Messaging
WSDL mode support for both client and server side
REST Support

and many more... Try it with your self, WSF/Ruby brings the power of Ruby and Web Services into one space desk :-)

WSO2 provides the support for Web Services in a number of languages including Java, C, Perl, Ruby and so on... You may have a look at the developer portal for more information.

How To convert the jar artifacts into OSGi bundles

2008-07-22T06:34:00.004+05:30

As I have pointed in my previous blog OSGi is getting more and more attraction of the Java community and it is becoming the de-facto standard for supporting multiple versions of the same libraries being used in the same environment. Because of that it is good if we could release OSGi compatible artifacts (OSGi bundles).

There are 2 ways of converting the jar artifacts into OSGi bundles each of having its own pros and cons.

If you are using Apache Maven as the build system, probably you will be using the maven jar plug-in to produce jar files out of your maven project modules, and the difference between the jar artifact and the OSGi bundle resides in the MNIFEST.MF file. So converting this jar artifact into the OSGi bundle is just a matter of changing the maven plug-in used to generate those artifacts. In fact you will need to use the maven bundle plug-in instead of the maven jar plug-in.

Well, yes it is just changing the build plug-in in the maven pom.xml, but this plug-in is not that easy to configure. Bundle plug-in needs to be configured to reflect the required information into the MANIFEST.MF file.

Here is a set of configurations that has to be present in the bundle plug-in in order to configure it correctly;

bundle-version

Bundle version has to be started with a digit and should follow the OSGi bundle versionning convention {major}.{minor}.{micro}.
[Note: SNAPSHOT being the version number is not going to work for the OSGi bundles]

bundle-name

Name of the bundle that you produce which is normally goes with a group id of the maven module; for example org.apache.synapse.core

bundle-symbolicname

Most of the times same as the bundle-name but can be different as well. This entity is used to refer to this bundle in the OSGi environment.

private-package

Packages that are used within this module and you do not expect these packages to be used by any of the parties that are using this bundle.

export-package

Packages that are exported to the users of this bundle, probably you will need to export the root package and all its subsidiaries; for example org.apache.synapse.*;

import-package

Packages that are used within this bundle classes and not resides in this bundle, basically everything that you depend on

If you look at the above list you will realize that OSGi bundles are all about packages, and you can specify the resolution of these to be optional in which case they will be loaded on demand. Also you don't need to put each and every package name that you are using in the import-package spaces but the bundle plug-in will try to use it's intelligence to add the packages that you are using at the bundle generation time.

If you want to have a look at a sample plug-in configuration you may have a look at the synapse core module pom.xml. One last thing is that you need to change the packaging of the module from jar to be bundle.

This is how you make the jar file itself to be a bundle, and it is possible to make a bundle out of an existing none OSGi jar file as well. This is just a matter of wrapping the existing jar file with a new jar which is configured as a bundle. You may have a look at some of the jar files being converted to OSGi bundles in the WSO2 space, while creating the OSGi compliant product stack

Apache Synapse artifacts are OSGi compliant

2008-07-21T10:33:00.005+05:30

Apache Synapse provides an open source Enterprise Service Bus which is implemented in Java. Version support and modularized hot update mechanism is one of the areas where Java is lacking for the moment. OSGi (The Dynamic Module System for Java) provides a mechanism to support versions and the hot update features on an OSGi container for Java libraries (jar).

Having said these, we (Synapse community) has made the synapse artifact jar files into OSGi bundles making the ability to use the artifacts inside an OSGi container without any problem. Even though these jar files are now OSGi bundles, that doesn't prevent these artifacts being used as native jar files, so it is backwards compatible. Interestingly, this change just resides in the MANIFEST.MF file in the META-INF folder of the jar file.

So, what am I getting from Synapse artifacts by them being OSGi bundles?

Hhhmmm... Good question, well, if you are not using an OSGi container to make these bundles available to your application (assuming you are using synapse artifacts within your application), then there is not much value of synapse artifacts being OSGi bundles.
[Note: Standalone Synapse server is not yet an OSGi container]

Probably this will be a starting point for Synapse server to be an OSGi environment ;-)

Apache Synapse ports registered under IANA

2008-07-15T21:52:00.002+05:30

Apache Synapse was using the following ports as its HTTP and HTTPS transport ports from a while ago and now it is registered with IANA

The following links shows these ports listed in the port listings first of which is managed by IANA itself and has been considered as the official registered ports and the other is a WIKI page which describes the widely used ports and the corresponding products.

[1] - http://www.iana.org/assignments/port-numbers
[2] - http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

Further my previous blog explains how to register any port with IANA for a product.

Registering a port number for a product

2008-07-15T11:18:00.004+05:30

There is one single place where you can find all the registered port numbers for specific products which is IANA. IANA stands for the Internet Assigned Numbers Authority, and as the name depicts this is the place where you should look for official registered ports for a product.

That being said, I must appreciate the set of people who works for this organization because I was able to get Apache Synapse ports registered without any hassle and their service is fairly good. I just had to fill in this form and wait for them to finish there work and that's it.

So now how can I find the ports that are assigned to a particular product or how can I find the available ports?

Yes, here is the answer for that. This document displays all the registered ports under IANA including well known ports.

Well, is that the only place that I have to look for, before getting a port registered to my product?

Yes and No.

Yes, because those are the set of ports that are officially registered and you will be able to register any port which has not been listed there.

No, because there are commonly used ports that are not registered under IANA.

Then, where can I find those ports?

There is a WIKI page which collects all the widely used official and unofficial ports, so it is better to have a look at that, before selecting a port for the product.

It is better to register the ports that are being used with products so that there are no conflicts in ports and you will not see the following :-)

Good bye to the java.net.BindException!!!

Open Source IDE for Apache Synapse

2008-07-03T11:42:00.004+05:30

Yesterday one of my friends asked from me about IDE tool for Apache Synapse.

My answer for him was to have a look at WSO2 ESB

Well, from my point of view it is still far away from being a fully fledge IDE for Apache Synapse because it is lacking on debugging capabilities, but it has a considerable amount of integration for Synapse. I must say it fully supports development and most of the management tasks.

I am proud to be a core developer of both Synapse and WSO2 ESB and would like to introduce WSO2 ESB as a tool which is even better than just an IDE to Apache Synapse, it does have some more functionalities and more mediators, for example router mediator. You should download it and use it to see how effective that is.

While all the above is true I must also say that there are no tools for existing IDEs to integrate with to my knowledge. But...... I am in the process of writing a schema for the Synapse Configuration Language which can be used with most of the IDEs for development purposes, but again from the point of debugging we are still lacking.

Context Sensitive Grammar (CSG) in XML

2008-06-28T20:34:00.002+05:30

I have started looking at the XML Schema because I wanted to design a Context Sensitive Grammar for Apache Synapse using XML Schema.

It seems an interesting work and I found this a bit old but very helpful article on CSG in XML Schema on w3.org

If you ever need any information with regard to CSG and using XML Schema to achieve context sensitive rules you may refer to this interesting guide;

http://www.w3.org/2000/04/26-csrules.html

The other fact is that you can await for an XSD for Synapse Configuration Language

The fastest open source ESB downloads

2008-06-28T19:39:00.003+05:30

Open source ESBs out there, please beware;

If any one ask for the fastest open source Enterprise Service Bus (ESB), I would say it is Apache Synapse / WSO2 ESB because of this study on the ESB performance.

I have noticed an interesting graph on the download stats. On the week after this article you can see an awesome peak and you can observe it below.

Source: http://people.apache.org/~vgritsenko/

WSO2 ESB uses Apache Synapse engine for the mediation and hence all that performance is from Apache Synapse, and it seems developers got this point and they have started evaluating it.

I would like to bring an another point into your attraction, which is about the user list of Synapse and you can see the trend clearly shows the growth of the project.

WSO2 ESB Performance Benchmark

2008-06-23T18:44:00.006+05:30

In my previous blog I have posted about the 1.7 release of the WSO2 ESB and here we go with more interesting data about the product with compared to other open source as well as proprietary competitors.

WSO2 ESB is based on the Apache Synapse engine and more specifically this version depends on the Synapse-1.2 engine. As a side note I am proud be the release manager of that awesome product :-).

What we have found after the performance tests is much interesting and we found that one of the proprietary competitors has shown a drastic improvement on its performance. It even beats WSO2 where as it was lying way down on the first phase of the performance tests which we did with the 1.0 version of the WSO2 ESB.

We have implemented the performance tests for three scenarios namely;

Direct Proxy (Pure Virtualization)
Content Based Router
XSLT transformation

I was responsible for building these three scenarios with the Apache Servicemix and I must say that it beats WSO2 ESB (Apache Synapse) on XSLT transformations for the 5K messages scenario. I think this is because they are using SAXON and it seems to be faster in transformations than the one we use which is XALAN. Any way I have to say that I found an issue with servicemix when trying to build a proxy service with it, because neither the servicemix-http nor cxf-bc binding components were not capable of forwarding the SOAPAction correctly to the target service.

One more thing that I have learned from this work is that JBI is adding more complexity to your integration solution, where as Apache Synapse is very simple to configure. Even though Mule, (which is one of the open source ESBs that we have benchmarked) is not based on the JBI specification I found it even harder to configure. May be I am wrong here, but I think you always need to write Java code to implement any integration solution.

If we look at the figures,

Mule continues to be in the worst position among all these products that we have benchmarked.
Servicemix shows a little better figures especially in XSLT
The proprietary ESB has shown a huge improvement.
WSO2 ESB is the fastest open source ESB on the ESB community.

Case Study on WSO2 ESB

2008-06-12T22:38:00.008+05:30

The Case Study referenced below describes;

Proof of Concept on Exposing EJB and WS Repositories using Service Aggregation, Utilizing WSO2's Open Source ESB

http://wso2.org/library/3325

This explains how you can use WSO2 ESB to expose two repositories which are accessible via a Web Service and an EJB respectively and merging results from both to provided the service functionality of a composite repository. At the same time this case study presents how to propagate security credentials from different security protocols to any other security protocol (for example UsernameTalken security to JASS for EJB)

Have fun :-)

Composite Services with Apache Synapse

2008-06-12T22:05:00.000+05:30

Synapse Proxy Services

If you are familiar with Apache Synapse then the term Proxy Service in Synapse should also be very familiar with you. In-case if you haven't tried Synapse yet please try that. This article on Synapse Proxy Service will cover up the ground of proxy services in detail and at the end of this article, a real life integration scenario will be explained with a sample using the Proxy Services operation model. At the same time, this article will walk you through the pros and cons of the proxy services inside Synapse.

Even if you are very familiar with Synapse and Proxy Service it is worth in having a look at this article because it presents how to implement a Composite Service using Synapse, in the last section of that article.

The content on this article in brief is as follows;

Apache Synapse 1.2 released

2008-06-10T14:32:00.000+05:30

Apache Synapse offers connectivity and integration with a range of
legacy systems, XML-based services and SOAP Web Services. It supports
non-blocking HTTP and HTTPS using the Apache HTTPCore (http://hc.apache.org)
components, as well as supporting JMS (v1.0 and higher) and a range of
file systems and FTP sources including SFTP, FTP, File, ZIP/JAR/TAR/GZ
via the Apache VFS project (http://commons.apache.org/vfs/filesystems.html).
At the same time Synapse 1.2 release adds the support for the Financial
Information eXchange (FIX) an industry driven messaging standard through
QuickFixJ, Hessian binary web service protocol, as well as other functional,
stability and performance improvements. Synapse supports transformation and
routing between protocols without any coding via configurable virtual services.

Synapse provides first class support for standards such as WS-Addressing,
Web Services Security (WSS), Web Services Reliable Messaging (WSRM),
Throttling and caching, configurable via WS-Policy upto message level,
as well as efficient binary attachments (MTOM/XOP).

The 1.2 release contains a set of enhancements based on feedback from
the user community, including:

Support for Hessian binary web service protocol
FIX (Financial Information eXchange) protocol for messaging
WS-Reliable Messaging support with WSO2 Mercury
Support for re-usable database connection pools for DB report/lookup mediators
Support for GZip encoding and HTTP 100 continue
Natural support for dual channel messaging with WS-Addressing
Cluster aware sticky load balancing support
Non-blocking streaming of large messages at high concurreny with constant memory usage
Support for an ELSE clause for the Filter mediator
Ability to specify XPath expressions relative to the envelope or body
Support for separate policies for incoming/outgoing messages
Support for a mandatory sequence before mediation

The combination of XML streaming and asynchronous support for HTTP and HTTPS
using Java NIO ensures that Synapse has very high scalability under load.
Performance tests show that Synapse can scale to support thousands of
concurrent connections with constant memory on standard server hardware.

Apache Synapse ships with over 50 samples
(http://synapse.apache.org/Synapse_Samples.html)
designed to demonstrate common integration patterns "out-of-the-box",
along with supporting sample services, and service clients that
demonstrate these scenarios. Apache Synapse is configured using a

straightforward XML configuration syntax

(http://synapse.apache.org/Synapse_Configuration_Language.html).

Apache Synapse is openly developed by a community that welcomes all
forms of input, ranging from suggestions and bug reports to patches and
code contributions. Your comments and feedback on the project and release
are welcomed.

The Apache Synapse code and binaries are available from the website

An odd & exciting experiance

2007-11-02T19:51:00.001+05:30

It was 17:03 2nd of November 2007 in Sri Lanka (LKT) and I was coming home by an intercity bus after finishing the work @ WSO2 (we were very busy with synapse 1.1 release and had a lot of things to do in my mind to the night). I was about to see my girl friend and was supposed to be in Ambalangoda (my home town) bus station at 17:00 (so already 3 minutes late :) )

I got late to come out of office today but was very happy because the bus I got in to is running fast and I thought I will be able to make it. But this driver was cought by trafic police for fast driving near Benthota which does not affect his speed even after that fine. I was in the front seat next to the driver.

But ... But ...

We were on a bend very near to Ambalangoda and just saw an Ashok Leyland bus coming on our lane towards us overtaking a same type of bus which was on the right lane. Ahhhhh!!!! My eyes got closed in a nanosecond and my mind is just blank. I heard a knocking sound in another millisecond with a shouting sound most probably of the driver. I tried to open my eyes, but was frightened and unable to open them. Nothing was coming to my mind, I can't see anything, not hearing anything and I felt sleepy. So I just staid right there for about a minute and carefully opened my eyes. There was a black smoke around and dashboard of the bus was just one millimeter away from me and saw the driver was stuck and tightened to the dashboard.

I feel other people getting down from the bus but I was unable to stand because of the dashboard, I doubt about the condition of my legs and tried to move them. I felt like getting better and people gathered around the bus and tried to pull the driver away by pulling the dashboard. Because of that I was able to stand and get on to the seat and jump out from the window. Hhhhmmmmm.... Nothing has happened to me, not even a small cut. I wonder about that and I think I am the most fortunate person on this earth on that time. But I got very excited and frightened, I think it is my laptop which saves me from the dashboard which was on my lap.

After about 30 minutes I got in to another bus and came to the bus station. Finally I met my girl friend, even though I am late she has not scold me because I got these photos from my mobile phone. If I did not get those photos she wont believe me, because she know I am lying to her with many explanations when ever I am late. When I returned home, I have opened my laptop and started it to see the condition even before telling this incident to my parents. It was working fine

Hhmm ... What a lucky day, I will never get in to the front seat again.

Article on Apache Synapse

2007-08-17T07:56:00.000+05:30

I have just published an article on Apache Synapse in the WSO2 OxygenTank which is the developer portal for the web service developers.

Apache Synapse is a mediation framework for Web services, based on the Apache Axis2 project, a set of XML, security, and Web services related projects and standards. Synapse provides a lightweight service bus and the basic infrastructure for the implementation of a Service Oriented Architecture (commonly known as SOA). In this article, you will learn the basic architecture of Synapse and how to configure it. In later parts you will be able to see some sample configurations with real world scenarios.

Read Full Article

This article is the first of a series of articles on Apache Synapse. In this series, you will learn what Synapse is, how it works, and how you can use it to solve common problems in the enterprise. You will understand some of the advanced features of Synapse, how you can extend it, and also some of its limitations.

WSO2 Caching - Something more to yet another Axis2 module

2007-06-22T08:42:00.000+05:30

Caching enables clients to reuse its data, minimizing the network usage and maximizing the execution speeds. One set of good examples for caching is the Web Servers and the Web Browsers. In other words, caching should improve performance, but most importantly without delivering expired or wrong data to its clients. Client should be able to inform the server if it wants to by pass caching and server *MUST* consistently act according to the client. These are clearly defined in the HTTP 1.1 specification under HTTP Caching.

With keeping all these ideas in mind, we have looked at the possibility of using this concept in Web Services space to improve its performance. Result was the initiation of the WSO2 Caching module, which will be soon available under Apache license.

This will be a server side as well as a client side web service caching implementation for WSO2 WSAS and Axis2. For the moment this will efficiently operate on the HTTP transport through the E-Tag using the Cache Control HTTP header, which will be generalized to SOAP level header in the very near future, enabling almost all the transports to get the efficiency of this module.

According to the current architecture, each and every request comes to the Axis2 Server (provided that caching module is engaged) will be identified with a unique XML node identifier such as DOMHASH value of the SOAP body and will be checked for the responses in the cache. If there is an unexpired response, caller will be served with that response and if not, request has to go through the general path and get the response, cache it for the future requests and serves the caller. When the response goes to the caller the identifier of the request will also be sent to the client as an E-Tag.

Form the client side, once the client gets the response to a particular request it will be cached in-memory with the E-Tag value sent by the server. For any subsequent requests to the server of the same request, client will be sending the E-Tag with the request. Server will examine the E-Tag for the presence in the response map before generating the unique request identifier and if found will be taken as the Unique identifier.

This is still under the development, if you are interested, feel free to go through the code @ our svn and all the feedbacks on this are more than welcome.

WSO2 ESB 1.0 - Fulfilling the needs of SOA

2007-06-12T08:35:00.000+05:30

On Monday 11th June 2007, we have fulfilled the existing needs of the Service Oriented Architecture.

It was a tremendous effort of the WSO2 ESB Team to bring this open source middle ware to 1.0

Key features of the WSO2 ESB 1.0 include:

* The non-blocking http/s transport permits ultra-fast execution and support for large numbers of connections. Because the WSO2 ESB automatically optimizes the parsing of messages, it can perform virtualization and routing with sub-millisecond overhead. In addition it can support thousands of simultaneous connections.

* Proxy services enable mediation of services without the need for coding; they include transport (HTTP/S, JMS, SMTP), interface (WSDL, Schema, Policy), message format (SOAP, POX), quality of service (WS-Security, RM), and optimization switching (MTOM, SwA). For example, the WSO2 ESB can be used to simply bridge between an XML message interaction on IBM’s MQSeries middleware and a Web service call on a Microsoft .NET server.

* An integrated registry/repository facilitates dynamic configuration, meaning that administrators can manage the ESB without having to bring the system down. The WSO2 ESB also includes built-in support for external registries, allowing resources to be centrally managed and refreshed as necessary without having to bring the systems down.

* Throttling, load balancing and failover controls optimize availability and help to manage and maintain service-level agreements.

* The light, feature-rich AJAX Web-based administration console facilitates monitoring, management and definition of policies, routing and transformations.

* Configuration model support includes XSLT, XPath, Java, Ruby, and Javascript, providing administrators with maximum flexibility.

Advanced XSLT transformations with an development experiance

2007-05-24T08:10:00.000+05:30

XSLT is a powerful Turing complete programing language, even though most of the developers do not use the powerful advanced features of XSLT. Which implies that, this blog entry is not going to be an introduction to XSLT.

Have you ever came across a situation where you have to do a common task for a group of XML nodes followed by the node specific tasks, using XSLT transformations? Yes I do...

I have done this when we are developing the WSO2-ESB administration console @ WSO2 which is an AJAX console to administer and monitor Apache Synapse and much more...

Here is our scenario

In WSO2-ESB/Synapse there is an element called "sequence" which is used to hold a set of "mediators" (mediators are the atomic components for message processing inside ESB/Synapse) bundled in to a single reference. Theses sequence definitions and all the other elements to configure ESB is fed to the system through the Synapse Configuration Language (XML based commanding language for Synapse). When we are trying to find a way to visually represent these sequences by keeping the following facts in mind, we have realized that the best fitter is XSLT.

It should be able to add another mediator visualization as extensions
It should be a maintainable code (XSLT or what ever...)
And most importantly, there should be a framework facilitating all the mediators with the common controls for tasks like move mediators up and down, delete them, add new one and so on. So that, adding new mediator visualization on top of this framework would add those controls to the new mediator as well keeping the main theme intact

Solution using XSLT and a little bit of JavaScript;
XML node of the sequence is something like the following, in this case which contains three mediators namely "log" followed by "send" followed by a "drop".

<syn:sequence name="testsequence" syn="http://ws.apache.org/ns/synapse">
    <syn:log level="full" separator=","/>
        <syn:send>
        <syn:endpoint>
            <syn:address uri="http://www.wso2.org/testservice"/>
        </syn:endpoint>
    </syn:send>
    <syn:drop/>
</syn:sequence>

Using the "mode" and "priority" attributes of the "xsl:template" element we have come up with a design to solve this. The structure of the XSLT in the framework looks as follows.

mediator_view.xsl

xsl_includes.xsl

drop_view.xsl
log_view.xsl
send_view.xsl

By putting a common template match to get all the elements in to the mediator_view.xsl with a higher priority value, we were able to add the common controlling tasks to each and every element of the sequence qualified with Synapse namespace. Apart from adding these common controls for the mediators we have inserted a xsl:apply-templates tag selecting the current node, (Note that, if you do not specify the selection to the apply-templates, XSLT processor will consider the childnodes of the node current as the selection) and parsing the mode argument as "custom" to the apply-template. As you can see in the above structure, there are XSLTs for each and every mediator in which the mediator specific template match with the mode value set to "custom" with a lower priority exists, for the mediator specific visualizations. After all,in the mediator_view.xsl, we stated a normal xsl:apply-templates tag to recursively generate the mediator visualizations in the sequence.al xsl:apply-templates tag to recursively.

This is how our mediator_view.xsl looks like,

<xsl:stylesheet version="1.0" xsl="http://www.w3.org/1999/XSL/Transform" 
                         syn="http://ws.apache.org/ns/synapse">
    <xsl:template match="syn:*" priority="0">
        <!-- code for the common controls -->
        <xsl:apply-templates select="." mode="custom"/>
    </xsl:template>
</xsl:stylesheet>

This is a sample XSLT for a mediator specific visualization (in this case for the send mediator),

<xsl:stylesheet version="1.0" xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="syn:send" mode="custom" priority="2" 
                          syn="http://ws.apache.org/ns/synapse">
        <!-- code for the send mediator specific visualization -->
    </xsl:template>
</xsl:stylesheet>

Here is how our visualization looks at the end of this processing,
