[Pub] Open Source ESB Mule

In the current issue of the Java Magazin I published my second article focusing on Enterprise Service Bus. This article illustrates the concepts and basic functionalities of an ESB based on the Open Source ESB Mule. In order to make the illustration more manifest I (supported by Werner Guttmann) implemented a prototyp with Active MQ, JBPM and Mule. A description and a download of the prototyp is available here.

Mule ESB is one of the most used Open Source integration platform in the Java community. This article describes the major components of Mule, such as:

• Mule Architecture and the programing model of Mule
• Service Components (alias Universal Message Objects)
• Endpoints, Routers, Filters
• Available Transports and how a transport is organised
  

On March 31, Mulesource announced the major Mule 2.0 release. The new version of Mule comes with a complete new schema-basd configuration style based on Spring 2.x (Enxtensible XML Authoring). Configuration should be easier as before.

As Mule 2.0 uses Spring as default configuration mechanism Mule user can also use Spring cababilities without thoughts, like:

• Spring AOP
• Springs transaction management
• Resource handling of Spring
• and many other features (DI, ...)

A full list of what is new in Mule 2.0 can be found here. At present many extensions around Mule, available on Muleforge, will be updated to Mule 2.0. After updating the prototyp on Mule 2.0 I will write an extra blog with my impressions about the new version. So for this time, I'll suggest to download the prototyp and see the power of Mule.
