[jboss-user] [JNDI/Naming/Network] - NPE in java.io.ObjectStreamClass.getClassSignature on lookup

[ron.piterman]

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
