[jboss-user] [EJB 3.0] - Re: @EJB injection in JBoss 5 application clients?

[Wolfgang Knauf]

I placed a sample at http://www.informatik.fh-wiesbaden.de/~knauf/private/Stateless_BrokenAppClient.ear (created with Eclipse/WTP and includes sources). Hopefully, someone can take a look at it and tell me whats wrong.

The app client is this:
public class GeometricModelApplicationClient
  | {
  |   @EJB()
  |   public static GeometricModelRemote geometricModel;
  |   
  |   public static void main(String[] args)
  |   {
  |     ...
  |     double dblVolume = geometricModel.computeCuboidVolume(10, 5, 7);
  |     ...
  |   }
  | }

I have no deploy descriptors in the app client project (actually, "application-client.xml" and "jboss-client.xml" exist, but are renamed so that they don't work).

Deploying this sample results in:
 21:03:16,921 ERROR [AbstractKernelController] Error installing to Real: name=vfszip:/C:/temp/jboss-5.0.0.CR2/server/default/tmp/jsr88/Stateless.ear state=PreReal mode=Manual requiredState=Real

If I add "jboss-client.xml", the error is gone, but my EJB variable is always null.
I tried to add a "jndi.properties" file, but this did not make any change.

By declaring an environment reference and performing a JNDI lookup, I can access the bean.

Thanks

Wolfgang
