The EJB3 support in that version was only a technical preview. If you are really just starting out to learn Java EE and EJB3, you should download and use JBoss AS 5.1.0.   Also, for name not found exceptions, this wiki page should help: http://community.jboss.org/wiki/DisplayTheJDNITreeWithTheJMXConsole -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521534#521534
