EntityManager injection Failure with Multiple persistence-unit of Jboss6

[zhang.hongyu]

hi,  I got a problem when inject the EntityManagar in Jboss 6.0.0.  we have two persistence-unit defined in the persistence.xml which are

  <persistence-unit name="PU1" transaction-type="JTA">

      <provider>org.hibernate.ejb.HibernatePersistence</provider>

...

   </persistence-unit>

  <persistence-unit name="PU2" transaction-type="JTA">

      <provider>org.hibernate.ejb.HibernatePersistence</provider>

...

   </persistence-unit>

The  persistence-unit will be injected in two Stateless bean like

Class A {

    @PersistenceUnit(unitName="PU1")

    private EntityManagerFactory emf;

    public String getEMInfo(){

        /* PersistanceUnit name is mapped as "hibernate.session_factory_name" */

        return emf.getProperties().toString();

    }

}

Class B {

    @PersistenceUnit(unitName="PU2")

    private EntityManagerFactory emf;

    public String getEMInfo(){

        /* PersistanceUnit name is mapped as "hibernate.session_factory_name" */

        return emf.getProperties().toString();

    }

}

Everything is packed in one EAR file and the depoly was successful without error. Howerver when I invoke getEMInfo() from both bean it give me the same result!  It shows the injected EntityManagerFactory are bound with PU1.   How can I fix this?

And  the output result changed after re-depoly! sometime to PU1, sometime to PU2

I got exactly the same. Multiple units in persistence.xml and they vary every deployment. I havent solved it yet.

I would like to make sure we get this right for AS7.  I started a test here https://github.com/scottmarlow/jboss-as/commit/d704226cca85d8e870f5ac91254bc816c0dd2475 that is not yet done (hopefully with be soon).

Looks like we are good in AS7. 

The AS7 unit test for the above issue, is passing.  Source is at https://github.com/scottmarlow/jboss-as/commit/c3ebdf0651aa91e92a0a35a018a3502943a6e1af

I also added some trace logging to help see what is going on during the search for the persistence unit:
