"Enterprise integration remains harder than it really should be. While integration is inherently complex, I felt that one of the major stumbling blocks is the lack of a common vocabulary and body of knowledge around asynchronous messaging architectures used to build integration solutions. Under the guidance of Martin Fowler and Kyle Brown, I teamed up with Bobby Woolf to create such a language in the form of 65 integration patterns" That's a phrase from the introduction of the book "Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions" by Gregor Hohpe,  Staff Software Engineer, Google Inc. and Bobby Woolf. If you talk to any Enterprise Service Bus(ESB) vendor/developer or a SOA architect, you'll never found a person who haven't read 'Enterprise Integration Patterns' book. Even some ESB vendors use the pattern templates(same images etc.) discussed in the book for their graphical flow designing tools of ESB (eg. F...

It's almost a year since the last and the very first WSO2 Con which was held in 2010. It was a successful conference where we divulged the power of WSO2 product stack and WSO2 Cloud Platform: Stratos. Things have dramatically changed this year and WSO2 Con 2011 will be one of the major event in the world of SOA and Cloud Computing. And could find a best time to blog about it, because WSO2 has just  won the "The best open source data center and cloud software" in Bossie Awards 2011 . WSO2Con 2011 is one fantastic week of tutorials, tech talk and networking events. Whether you are a developer, architect, IT manager or technology enthusiast, learn how global enterprises, SaaS providers and innovative startups are using WSO2 platforms to build distributed web apps, java services, bpel flows, Software-as-a-Service (SaaS) and more. And it comprises of the speakers from more than 10 countries... including Industry Leaders from eBay, IBM, Google, Cognizant, T-Mobile, Two De...

WSO2 ESB v4.0.0 Released - 13th June 2011 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 4.0.0 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, an...

In the modern enterprise, complex business requirements are increasingly satisfied by a combination of new and existing services. Getting the right bits of information at the right place, at the right time, in the right format, and with the right protocol can be a challenge. The WSO2 Enterprise Service Bus (ESB) provides a simple solution to this integration problem by providing a rich set of integration capabilities for robust, scalable and seamless integration of such services. Topics covered include: Understanding the basics: mediators and mediation flows, proxy services, endpoints End-to-end scenario on service integration using the WSO2 ESB Heterogeneous service integration and complex message mediation features.

In some cases you won't be able to transfer very large files using storage devices. So the best way is to use split a given file in to arbitrary no of volumes at the source and them merge at the destination. This will simply do that for you. Splitting Say you have a directory/file called 'foo'. First you need to create a '.tar.gz'. tar -cvzf foo.tar.gz foo Then you can split it using split command and as a parameter you can give the size of a each volume. (here its 25MB) split -d -b25m foo.tar.gz foo.tar.gz. Merge Simply you can merger using the cat command. cat foo.tar.gz.0* >foo.tar.gz Now you can untar this and use the original file/directory.

The first ever WSO2Con 2010 was successfully concluded on 15th of September 2010. It was a giant step in the Sri Lankan Software Industry where a Sri Lankan based company was able to held a world class conference that touches the cutting edge technologies in the Enterprise Middle-ware world. Being a member of the WSO2Con samples team, I was involved in the development of the sample scenario on the perspective of WSO2 ESB. It was an exciting couple of days that all of us worked with tremendous determination of making it a success. So, finally it paid off.. everything went very smoothly and the demo was a near perfection. Both Carbon and Stratos demos of the shopping cart app was a real success and we were able to use most of the WSO2 Products in that demo. Azeez's presentation of the demo on top of Cloud went really well. Panel Discussion I developed the ESB related configurations and integrated the all the components through the WSO2 ESB. I would like to explain the complete scen...
