It is getting strange. When I run my client code (JUnitTest) in debug mode with a breakpoint set, everything works fine now. But in normal mode I still get the exception: javax.naming.NameNotFoundException: remote not bound I really don't understand what's going on. What's different in debug mode? Maybe the jar files I need in classpath: Which jars do I need for a remote connection with JBoss 4.0.5 and EJB3? I hope somebody can help me!
