Well we got an answer for you. Join our free webinar series this July. There will be four webinars in total ranging from an "Introduction to the WSO2 ESB" to more advanced scenarios such as "Using the WSO2 ESB and FIX - supporting Financial messaging".
FIX support is the latest addition to the WSO2 ESB which is available in the recently released 1.7 version. This series of webinars will be presented by Paul Fremantle, CTO at WSO2 together with Asankha Perera ( ESB Architect), Asanka Abeysinghe (Architect) and Ruwan Linton (Senior Software Engineer).

Increasing memory given to maven using MAVEN_OPTS did not solve the problem. As this setting just increases the memory given to the build process and not the individual test cases. The solution was to use the following configuration in the surefire plugin.
<argLine>-Xms256m -Xmx512m</argLine> <testFailureIgnore>false</testFailureIgnore>
The pom for the integration test can be found here. This fixed the heap space issue and now we have our test cases running on the nightly build. You can see the status of our nightly builds at http://builder.wso2.org/browse/MASHUP-NIGHTLY
The Mule Enterprise Edition (Mule EE) violates item #6 which is described above. The License of Mule EE states that you cannot publicly publish performance results against it. Whats more if you go to the mule site you won't find the source code of Mule EE, rather it asks you weather you are "Looking for the open source Mule Community Edition?".
What baffles me is that Dave Rosenberg the CEO Mule states that "The Enterprise version of Mule is open source". Take a look at Dave's comment on Sanjiva's blog. What a joke.
Now Mule CE is an open source ESB. But would anybody care to use it in production? Look what we found out about Mule CE during some performance testing. 1% of all requests sent to Mule CE 2.0.1 fails. Now thats how you sell Mule EE keeping Mule CE Open Source.
The guys who knew Axis2 to some extent were able to make to most of this training, as we were able to question certain decisions made at that time.
Its also nice to note that except for Deepal. the rest are already reading for there PhDs. Deepal will be joining that list next month when he will head off for higher studies. Its also a interesting that the core Axis2 team has been associated with WSO2.
Deepal has also published his first book on Axis2 "Quickstart Apache Axis2" which is now available in the stores.
The Axis2 training was a great success so now its time to learn some policy. Again there will be no better person than Sanka himself, the person behind Apache Neethi (The policy engine used for Apache Axis2 as well as CXF). Once next week is done all of WSO2 will be policy experts too.
All of these are a part on continuous improvement to us.

There are many things that come in to play when deciding on which ESB to go with. Some of them are Performance, Licensing, Usability, Stability... etc. WSO2 has always been at the forefront when it comes to benchmarking ESB performance. You can find previous performance comparisons here and here. We've always been open as to how we conduct them and has always tried to get help from the relevant projects on how to configure them best.
Asankha the product manager of the WSO2 Enterprise Service Bus (ESB) recently published performance results based on its 1.7 release. The WSO2 Enterprise Service Bus (ESB) was compared with other leading implementations - both open source and proprietary. This comparison was done against a leading proprietary ESB, the proprietary version of an Open Source ESB, Apache Service Mix 3.2.1 and Mule Community Edition 2.0.1 (Mule CE). We cannot disclose the names of these proprietary ESB's cause they have a clause in there License saying that "Thou shalt not publish any performance results against us".
The results were pretty impressive. The WSO2 ESB outperformed all open source alternatives and it also outperformed the proprietary version of an Open Source ESB. Now what does that mean? The WSO2 ESB is the fastest open source ESB around (And thats with no specific performance tuning, Expect better results in the time to come.). The WSO2 Enterprise Service Bus (ESB) also displayed excellent stability on all scenarios.
Another interesting observation is that 1% of all requests sent to Mule CE 2.0.1 failing. Now who would want to use such a product in a production environment?

Paul has been listed as one of Infoworld's top 25 CTOs. This is a huge achievement for Paul as well as WSO2 (whom Paul is a co-founder of).
Take a look at what Paul himself has to say about this achievement. I agree with Paul a 100% about what he has to say about the culture at WSO2, "I strongly believe - and long may it continue - that WSO2 doesn't suffer from "Drive By Architecture" syndrome". WSO2 is flat structured, even though there are co-founders, CTOs, Product Managers and so on when it comes to a technical debate each and every member at WSO2 has a role to play. Their thoughts and ideas are taken seriously and is not looked down on.
The team spirit we have at WSO2 is tremendous and it's a pleasure to be a part of WSO2.

A living testimony to the development of open source in Sri Lanka is GSoC 2008. Where Sri Lanka was ranked 9th in the list of GSoc Applications and GSoc Accepted Applications. Not surprisingly a staggering number of applications from Sri Lanka came from the University of Moratuwa which is where I was privileged to have had my Higher education at. The University of Moratuwa ranked 1st in both the number of Applicants and number of accepted applications.
