Try this. Place your mbean classes into the ear file (into an existing jar file or into a new jar file - don't forget to add it to the application.xml). Put your mbean description into a separate *-service.xml file and place it in the ear file also. Then add a META-INF/jboss-app.xml file with this entry: <jboss-app> | <module> | <service>xxx-service.xml</service> | </module> | </jboss-app> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4171594#...
