Don't find the good persistence unit when multiple ear with same pu name
------------------------------------------------------------------------

                 Key: JBAS-5043
                 URL: http://jira.jboss.com/jira/browse/JBAS-5043
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: EJB3
    Affects Versions: JBossAS-4.2.2.GA, JBossAS-4.2.1.GA
         Environment: JBoss 4.2.2 on linux Red Hat 4 AS 4 or Windows XP, using Sun JVM version 5
            Reporter: Jerome Poittevin

When using multiple ear with multiple persistence unit having the same name, Jboss uses the wrong persistence unit when deploying ejb and the exception "Entity is not mapped" occures when entities are accessed.
This behaviour seams to be in contradiction with the Java Persistence API Spec (see § 6.2.2).

Example :
app1.ear and app2.ear with two persistence unit having the same persistence unit name "pu".

While deploying app2.ear, the following message can be seen in the JBoss log :
2007-11-30 15:13:03,865 DEBUG [org.jboss.injection.PersistenceUnitHandler] ***** adding PU dependency from located persistence unit: persistence.units:ear=app1.ear,unitName=pu

When accessing EJB deployed in app2.ear, the following exception occures :
javax.ejb.EJBTransactionRolledbackException: org.hibernate.hql.ast.QuerySyntaxException: TestEntity is not mapped [From TestEntity t where t.id = :id]

The following patch seems to make JBoss find the good persistence unit :

In file org.jboss.ejb3.enc.DeploymentPersistenceUnitResolver.java on line 106 :

replace :

if (deployment.getEntityManagerName().equals(unitName)) return deployment;

with :

if (deployment.getEntityManagerName().equals(unitName) && deployment.getKernelName().contains(deploymentScope.getBaseName())) return deployment;
