Hi micho, there is a "client" directory in your jboss installation. It contains nealry all needed libs for your client. Needles to say, that you do not need all of them, except you are using all kind of possible clients =) Additionally there are some libs, that are not in this folder: - cglib.jar - commons-logging.jar - ejb3-persistence.jar -> lib/ - hibernate3.jar -> lib/ - hibernate-annotations.jar -> lib/ - jboss-remoting.jar -> lib/ I think that all.
