Exception: javax.naming.NameNotFoundException

[terence]

I wrote a EAR application consisting of a servlet WAR and a session EJB JAR. The EAR was successfully deployed. The servlet invokes a method on the EJB but got thrown with :

Exception: javax.naming.NameNotFoundException: MyTestingEJB not bound body

My queries :
- Does JBoss 3.0, comes preconfigured with a JNDI naming service which starts up automatically when JBoss server starts up? Or do I have to set up own JNDI server?

- In JBoss 3.0, how do I bind the an EJB to a JNDI name?
What descriptor files must I set up?

- Any idea why I got the above exception and how to resolve it?

Thanks.

Yes.

By default the <ejb-name> is used as the JNDI name. You can override this behavior in jboss.xml file.

Probably something wrong with the deployment descriptor configuration, and you end up doing a lookup on the wrong name.

Thanks, but stil doesn't work.

Must I set up the web-client.xml and/or jboss-web.sml for the servlet to call the ejb? I am new to JBoss. I am an idea of jboss.xml but what do above two descriptor files do in JBoss?
