If your client is a J2EE application client that runs in our client
container, you need to configure it with an EJB reference in
application-client.xml and then resolve that to the specific EJB in
geronimo-application-client.xml. That way your client code will have
access to a java:comp/env JNDI environment and the EJB reference will
live in there.
If the client does *not* run in the client container, then you should
try looking up the EJB without the "java:comp/env/" prefix, so I would
have expected ctx.lookup("ejb/helloworld-ejb/HelloBean"); to work. If
it still does not, could you post the exception?
Thanks,
Aaron
