[jboss-user] [EJB 3.0] - Re: NullPointerException in JavaEEComponentHelper with JBoss

[japase]

Hi,

As suggested I've created a new topic regarding the EJB injection in web services (http://www.jboss.org/index.html?module=bb&op=viewtopic&t=154200).

I've also tried to test different configurations to surround the main problem (I have now a smaller application, but still build upon our framework, which seems behave in the same way as the "big" one, ifsapp.ear; we've also got a newer build of JBoss 5.1 through Red Hat support: 5.1.0.CR1; could it be of interest to get the log files from this version?).

But during my tests I found it totally impossible to deploy EJBs with mutual dependencies:


  | @Stateless
  | public class AStatelessSessionBean implements AStatelessSession
  | {
  |    @EJB
  |    //@EJB(mappedName="ifssimpletest/BStatelessSessionBean/local")
  |    private BStatelessSession bean;
  | 
  |    @TransactionAttribute(TransactionAttributeType.REQUIRED)
  |    public String sayHello( String name )
  |    {
  |       return bean.sayHello(name);
  |    }
  | 
  |    public String greetingPhrase()
  |    {
  |       return "Hello there";
  |    }
  | }
  | 
  | @Stateless
  | public class BStatelessSessionBean implements BStatelessSession
  | {
  |    @EJB
  |    //@EJB(mappedName="ifssimpletest/AStatelessSessionBean/local")
  |    private AStatelessSession bean;
  | 
  |    @TransactionAttribute(TransactionAttributeType.REQUIRED)
  |    public String sayHello( String name )
  |    {
  |       return bean.greetingPhrase() + ", " + name + "!\n";
  |    }
  | }
  | 

I've tested with and without 'mappedName'; I've also tested to pack both EJBs to a single jar file - nothing helps (I have a very simple test application with two EJBs as above and one servlet calling one of the EJBs - this application works perfectly on both GlassFish 2.1 and webLogic 10.3).
