Hi, Which profile from the JEMS installer are you using? (ejb3, ejb3-clustered) I can't see your boot log, but may be there are some boot errors about port conflicts. Try to close all your application before running the server - common source of problems are the internet browsers, IM, p2p programs etc. Make sure all other network applications are closed before running the server. I don't have any problems (using the latest CR1 and the latest sample seam apps). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3992266#...
