Hi saladinmundi, I advice you to use the Eclipse Web Tools Platform plugin (or the JBoss Tools plugin, which is based on this) to create/edit your EJB projects. You have to create a JBoss server, and have to create non-plain-Java-projects, but a WebTools specific "EJB project". This way, all required server JARs are on your classpath. Hope this very short explanation helps Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4233726#...
