[jboss-user] Problems in deploying two applications that have the same EJB bundled in

Hello, I'm having a problem deploying two applications where both applications use the same EJB jar file. The project worked and has been deployed succesfully on Oracle Application Server 10g but there's a need to migrate it to JBoss AS (4.2.2GA). So, if application A and application B are separately deployed to the JBoss application server they work fine but if I try to deploy them both they will broke. Both applications have this defined in the application.xml: <module> <ejb>backengine-ejb.jar</ejb> </module> What do I need to do to work around the problem? Here's the backengine-ejb.jar error debug log listing that occurs when trying to deploy application A if application B has already been deployed: --- BEGIN --- 2008-01-22 14:49:06,109 DEBUG
