If yes: remove them. -does the client use JBoss jars from another version as the server? If yes: always use the client jars matching exactly your server version. -does the client contain old ".class" files of your EJBs? If yes: update to the latest ones from your EJB project. Hope this helps Wolfgang -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537987#537987] Start a new discussion in EJB 3.0 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
