      Hi,

      I am trying to get jndi lookup to work and have the following exception on the lookup:

      java.lang.NullPointerException:

      I use jboss 4.0.5-GA with BEA JRockit 1.5.0_08

      On the client classpath are
      javassist 3.3
      jboss-ejb3-client 4.0.5-GA
      jbossall-client 4.0.5-GA

      I could not find anything similar in google or in this forum -

      The session bean I am trying to access : 

      @Stateless()
@Remote( TestSession.class )
public class TestSessionImpl implements TestSession {
 public String test() {
 return "hello";
 }
}


      and the remote interface: 

      public interface TestSession {
 public String test();
}


      these are deployed as a single ejb3-jar in the deploy directory of jboss.

      using the jmx console I can see the session-bean bound in the jndiview.

      Any idees ?

      Cheers,
      Ron
