We can now start up a new porcess with HumanTaks and Session persistence, but... SessionInfo never gets written to the database (HumanTask is persisted ok). The result is that when we try to load the session again it fails - this is excpected since we can not wrtite to the database. 
(We are starting Jbpm5 for a EJB context)

The problem now (which we can se in the Hibernate log)
[05/01/12 03:33:12:012 CET] DEBUG ast.ErrorCounter: throwQueryException() : no errors

I think this come for the setup of the Environment:
ttlog.logDebug("Creating EntityManagerFactory for persistant session");
    EntityManagerFactory emf = Persistence.+createEntityManagerFactory+("org.jbpm.session");
    Environment env = KnowledgeBaseFactory.+newEnvironment+();
    env.set(EnvironmentName.+ENTITY_MANAGER_FACTORY+, emf);


      When running i Junit mode (java SE we can use Bitronix and the line under works fine
              env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());

Do someone now how we can do the same in WLS? Or must we do someting else to tell Jbpm where to find the transaction manager?
