Jboss AS 7 - Dependency Injection

Im attempting to make use of dependency injection in Jboss AS 7 and im having huge difficulties.

I have setup a EAR which contains both a EJB jar and a war.

The war contains a richfaces web app.

Im attempting to inject an EJB from the ejb jar into a faces managed bean with the code below : 

 public class UserController {

    @EJB(mappedName="UserService")
    private UserFacadeService userService;

    public String getService(){
        if(userService == null){

however when i deploy jboss puts the error in the console : 

rolled back with failure message {"Services with missing/unavailable dependencies" => ["jboss.deployment.subunit.\"GoodByeJohnEAR.ear\".\"GoodByeJohnWeb-1.0-SNAPSHOT.war\".component.\"managed-bean.za.co.gbj.UserController\".START missing [ jboss.naming.context.java.module.GoodByeJohnEAR.\"GoodByeJohnWeb-1.0-SNAPSHOT\".\"env/za.co.gbj.UserController/userService\" ]","jboss.deployment.subunit.\"GoodByeJohnEAR.ear\".\"GoodByeJohnWeb-1.0-SNAPSHOT.war\".jndiDependencyService missing [ jboss.naming.context.java.module.GoodByeJohnEAR.\"GoodByeJohnWeb-1.0-SNAPSHOT\".\"env/za.co.gbj.UserController/userService\" ]","jboss.naming.context.java.module.GoodByeJohnEAR.\"GoodByeJohnWeb-1.0-SNAPSHOT\".\"env/za.co.gbj.UserController/userService\".jboss.deployment.subunit.\"GoodByeJohnEAR.ear\".\"GoodByeJohnWeb-1.0-SNAPSHOT.war\".module.GoodByeJohnEAR.\"GoodByeJohnWeb-1.0-SNAPSHOT\".2 missing [ jboss.naming.context.java.module.GoodByeJohnEAR.\"GoodByeJohnWeb-1.0-SNAPSHOT\".env/UserService ]"]}

First, make sure in your war, you have the file META-INF/MANIFEST.MF, and there has the line Class-Path: GoodByeJohnEJB-1.0-SNAPSHOT.jar,

Then in your UserController class, try to remove the mappedName, just add the EJB annotation.

Or, you can use this :

InitialContext ic = new InitialContext();
UserFacadeService userService = (UserFacadeService )ic.lookup("java:global/GoodByeJohnEAR/GoodByeJohnEJB-1.0-SNAPSHOT/UserFacadeBean");

It looks like the issue might be that your WAR doesn't have a dependency for your EJB jar defined. It's best to define a Class-Path entry your WAR's META-INF/MANIFEST.MF for your EJB jar files if you have not.

You might also want to check your configuration file and make sure the <ear-subdeployments-isolated /> tag is set to false.

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
</subsystem>

There is also some decent documentation on class loading in JBoss AS7.
