Thank you for your reply. That's what i was thinking, unfortunately... In fact, i managed to access to the entitymanager thanks to a session bean or a servlet, which both are on the server side, but not from my client... Too bad. A last question : do you think another container (Glassfish or another one) could have implemented that ? (i can dream, no ? ;-) ) Regards, Guillaume View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037857#...
