I am running JBoss 4.0.4.GA using Java 1.6 and am getting the following exception:

Exception in thread "main" java.lang.RuntimeException: javax.naming.NamingException: Could not dereference object [Root exception is java.lang.reflect.UndeclaredThrowableException]

The client code segment I have is:

private TravelAgentRemote getAgent()
{
try
{
agent = (TravelAgentRemote)getInitialContext().lookup("TravelAgentRemote");
}
catch (Exception ex){ throw new RuntimeException(ex);}
return agent;
}

and the session bean definition is:

@Stateful
@RemoteBinding(jndiBinding="TravelAgentRemote")
public class TravelAgentBean implements TravelAgentRemote {...}

If I change the session bean to be Stateless the client code works fine - what is different in JNDI naming for Stateless vs. Stateful session beans ?

Also, it has been reported to me (although not verified) that this code works fine with Java 1.5.

If you want to see the whole set of source, it is the source from Chpt. 11.4 from the O'reilly book "Enterprise Java Beans 3.0" by Burke & Monson-Haefel (ISBN-13: 978-0-596-00978-6).

Any insights would be appreciated.

Thanks.
