[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-879) Injection metadata in ejb-jar.xml does not override @EJB annotation

[Carlo de Wolf (JIRA)]

    [ https://jira.jboss.org/jira/browse/EJBTHREE-879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12448724#action_12448724 ] 

Carlo de Wolf commented on EJBTHREE-879:
----------------------------------------

The ejb-ref-name 'ejb/InjectedService' does not override the annotated @EJB field. It should be 'com.sadalbari.test.overrideinjection.impl.RecipientServiceBean/injectedService' as per EJB 3.0 16.2.2.

So in effect an additional ejb-local-ref is being created, while the original still points to the mapped name specified.

> 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
