         Environment: OS-System: Linux 2.6.16.27-0.6-smp,i386
Java VM: Java HotSpot(TM) Server VM 1.6.0-b105,Sun Microsystems Inc.

JBoss EJB 3.0 RC9 Patch 1
            Reporter: Justin


I have 2 stateless session EJBs, RecipientServiceBean and InjectedServiceBean.

RecipientService exposes a remote interface.  InjectedService exposes only a local interface and is injected into the 'injectedService' field of the RecipientServiceBean

--------------------------------------------------- RecipientServiceBean ---------------------------------------------------
@Stateless(name="RecipientServiceBean")
@Remote(RecipientService.class)
public class RecipientServiceBean implements RecipientService {
    
    @EJB(mappedName="overrideinjection/InjectedServiceBean/local")
    private InjectedService injectedService;

    public String saySomething() {
        return "Hello: " + injectedService.getResponse();
    }

}
--------------------------------------------------- InjectedServiceBean  ---------------------------------------------------
@Stateless(name="InjectedServiceBean")
@Local(InjectedService.class)
public class InjectedServiceBean implements InjectedService {

    public String getResponse() {
        return "This is the real service";
    }

}
---------------------------------------------------------------------------------------------------------------------------------------------------------

I now want to override the injection specified by the @EJB annotation to inject a stub service.  The stub service and ejb-jar.xml included is as follows
--------------------------------------------------- RecipientServiceStubBean ---------------------------------------------------
public class InjectedServiceStubBean implements InjectedService {

    public String getResponse() {
        return "THIS IS THE STUB";
    }
}

--------------------------------------------------- ejb-jar.xml ---------------------------------------------------

A dump of my JNDI view at this point

+- overrideinjection (class: org.jnp.interfaces.NamingContext)
  |   +- RecipientServiceBean (class: org.jnp.interfaces.NamingContext)
  |   |   +- remote (proxy: $Proxy61 implements interface com.sadalbari.test.overrideinjection.RecipientService,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject)
  |   +- InjectedServiceStubBean (class: org.jnp.interfaces.NamingContext)
  |   |   +- local (proxy: $Proxy56 implements interface com.sadalbari.test.overrideinjection.InjectedService,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
  |   +- InjectedServiceBean (class: org.jnp.interfaces.NamingContext)
  |   |   +- local (proxy: $Proxy56 implements interface com.sadalbari.test.overrideinjection.InjectedService,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)

---------------------------------------------------------------------------------------------------------------------------------------------------------

The result is that the injection is not overridden and the stub is not used in preference to the 'real service':

Hello: This is the real service

I can work around this issue  by removing the @EJB annotation and ALWAYS declaring the injection in the ejb-jar.xml in which case I get:

Hello: THIS IS THE STUB

Thanks
Justin
