It was just an idea... JBoss Messaging 2, is using MicroContainer, but that' s not available on JBoss 4. On JBoss 4, you would need to develop a service, and the way for doing is creating a MBean. You could have a JBM2MBean, instantiating and starting the server, the same way we don the embedded example. But I would rather migrate to JBos5. If you can try JBossMessaging 2, you probably can try JBoss 5. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4236161#...
