Message Driven Beans support in WebSphere Application Server 5.0
 Technote (troubleshooting)
 
Problem(Abstract)
Is the support for Message Driven Beans new to WebSphere Application Server 5.0?
 
Resolving the problem
EJB 2.0 specifications introduced a new type of bean called the Message Driven Bean. WebSphere Application Server 5.0, being fully compliant to EJB 2.0 specification, therefore supports Message Driven Beans.

Message Driven Beans are new in WebSphere Application Server 5.0. However, WebSphere Application Server Enterprise Edition Version 4.x provided extended messaging support, which had Message Beans. Message Beans and Message Driven Beans are similar in that they both implement the MessageListener interface, but Message Beans are in fact Stateless Session Beans. WebSphere Application Server 5.0 provides a tool to migrate version 4.x Message Beans to Message Driven Beans. This migration utility is called mb2mdb. It is a batch file in Windows systems and a shell file in Unix systems and is located in the WAS_install_root\bin directory.
