I am converting my jBPM 4.4 code over to use 5.0.1 and am trying to configure 
persistence.  When I run my unit tests to see if everything is working as it 
did in 4.4 I am getting this error:

No Persistence provider for EntityManager named org.jbpm.persistence.jpa

See the end for the full stack trace.  I have been following the user guide and 
configured a datasource.xml file and set up the EntityManagerFactory and used 
it in the creation of the KnowledgeSession.  What am I still missing?  Any help 
would be appreciated.

      EntityManagerFactory emf =
          Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );
      Environment env = KnowledgeBaseFactory.newEnvironment();
      env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
      Collection<StatefulKnowledgeSession> ksConfigs =
                                         kbase.getStatefulKnowledgeSessions();
      if (!ksConfigs.isEmpty()) {
        KnowledgeSessionConfiguration[] sessionArray = 
                         (KnowledgeSessionConfiguration[])ksConfigs.toArray();
        if (ksConfigs.size() == 1) {
          sessionConfig = sessionArray[0]; 
        }
        if (ksConfigs.size() > 1) {
          throw new Exception("More than one KnowledgeSessionConfiguration" +
            " object exists.  We were only expecting one");
        }
      }

      if (ksession == null) {
       ksession = kbase.newStatefulKnowledgeSession(sessionConfig, env );
      }
