Yes, that helped. Thank you. Does this mean, that I have to build different packages if I wish to deploy one of those Packages on a diferent Server? I hoped, that I could simply put this Package on a different Server and remap the JNDI Name to the remote object. But for this Situation there are the Interfaces missing. So this was not where its going with EJB3? Regards, Alexander View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977600#...
