Noxis, I'm trying to replicate this.. and I had played with several different versions, different configurations and I couldn't replicate this problem. Maybe you could modify the ejb3mdb example in such way to replicate this.. it would help a lot. In your example you are playing with sockets.. maybe there is something wrong with your sockets also.. I would need to take a look on logs to verify what's going on (Maybe this is something specific to your environment?). If you could replicate the problem in an independent manner it would help us a lot! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4076994#...
