[jboss-jira] [JBoss JIRA] (WFLY-12274) EJB Bean with mappedName is not binding

[Jaikiran Pai (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13757010#comment-13757010 ] 

Jaikiran Pai commented on WFLY-12274:
-------------------------------------

More of a FYI - Back when we started redesiging AS7 and the EJB3.x spec support for it, we had decided to _not_ support "mappedName" on these component declaring annotation (like the @Stateless annotation in this example). The javadoc of this attribute states that this value can be anything and not necessarily a JNDI name and may not be supported by application server vendors[1]. I don't have a reference to the discussion where we had decided this (it mostly was a IRC or such discussion from what I remember).

> EJB Bean with mappedName is not binding , the mappedName is vendor specific, it is not portable, however @EJB(mappedName=...) is expecting a global JNDI path, but @Stateless(mappedName=...) does not appear to be binding anything.
> {code}
> @Stateless(name="HelloBean", mappedName="MappedHelloBean")
> public class HelloBean implements Hello {
> ...
> {code}
> {code}
> @Startup
> @Singleton
> public class TestSingleton {
>   @EJB(mappedName="MappedHelloBean")
>   private Hello ejb;
> ...
> {code}
> So the @EJB causes the TestSingleton to fail.
