Simple example registering an EJB 3.0 bean into a WAR's ENC

[hallorant]

I've searched and searched and could not find out how to register an EJB 3.0 bean into a WAR's ENC.

If I have a session bean:

@Stateless
public class LogicBean implements Logic { ... }

Where the interface Logic is the remote and local interface. This is deployed into a Jar. And works fine in Jboss (via Java application clients). But I can't get it to talk to a WAR when it is deployed in an EAR.

Now I have a servlet

public class ExampleServlet extends HttpServlet {

 Logic agent;

 @Override
 public void init() throws ServletException {
 try {
 Context context = new InitialContext();
 Object ref = context.lookup("java:comp/ejb/LogicBean/remote");
 agent = (Logic) PortableRemoteObject.narrow(ref, Logic.class);
 } catch (Exception e) {
 throw new ServletException(e.getMessage(), e);
 }
 }
 ...
}

OK, hit post rather than preview...sorry

one line in the code is a typo, it should be:

Object ref = context.lookup("java:comp/env/ejb/LogicBean/remote");

My question is how to configure the web.xml and jboss-web.xml so that the servlet knows about my EJB? Can someone post or point me toward an example, using a EJB 3.0 bean, that explains how to configure the <ejb-ref> tag in both web files. Thanks in advance, I'v been playing with this for a few days and had no luck.

A second question relates to the first. What, besides the remote/local interface, classes related to the EJB need to be in the WAR for things to work? In the old days the container produced a client JAR, what does one do in EJB 3.0 in JBoss? Thanks!!
