NameNotFoundException: env not bound

[achoy]

When I tried to deploy some EJB classes in JBoss, it gives me the following error message:
*************************
[Default]
javax.naming.NameNotFoundException: env not bound
*************************
I used lookup in a few places in my code to look for another EJB, and they should be in the namespace of java:comp/env/ejb. I'm also using jboss.xml to over-ride the JNDI name, but it still doesn't work.

I also got the following error messages after the previous one mentioned above ...... does anyone have any clue what it means?
Please note that I've used "deploytool" to deploy to J2EE environment, and it worked over there.

JNDI question

Have you checked what your bean is bound to via the JNDI view app (http://localhost:8082/).

Where have you placed the jboss.xml file? In the EAR or the JAR?

Verifier

The verifier appears to be telling you that you have left out the exceptions in the throws clause in the Home interface.

Cheers,
