Hi

When trying to use jbpm5.1 in weblogic with persistance inside a EJB context we get an error like:

[05/01/12 02:13:14:014 CET] DEBUG impl.SessionFactoryImpl: Checking 0 named SQL queries
[05/01/12 02:13:14:014 CET] DEBUG persistence.SingleSessionCommandService: Instantiating  JtaTransactionManager
[05/01/12 02:13:14:014 CET] DEBUG jta.JtaTransactionManager: No JTA TransactionManager found at fallback JNDI location [java:comp/TransactionManager]
javax.naming.NameNotFoundException: While trying to look up comp/TransactionManager in /app/ejb/service-3.0.0.jar#ProcessControllerFacadeBean.; remaining name 'comp/TransactionManager'

        at weblogic.jndi.internal.AbstractURLContext.lookup(AbstractURLContext.java:130)
        at javax.naming.InitialContext.lookup(InitialContext.java:392)

I know we need to setup the TransactionManager but dont know how to do it. Can someone guide us i the right direction?

persistence.xml looks like:

  <properties>
  <property name=+"hibernate.dialect"+ value=+"org.hibernate.dialect.Oracle10gDialect"+ />
  <property name=+"hibernate.connection.autocommit"+ value=+"false"+ />
  <property name=+"hibernate.max_fetch_depth"+ value=+"3"+ />
  <property name=+"hibernate.hbm2ddl.auto"+ value=+"create"+ />
  <property name=+"hibernate.show_sql"+ value=+"true"+ />
  <!-- Echo all executed SQL to stdout -->
  <property name=+"format_sql"+ value=+"true"+ />
  <property name=+"use_sql_comments"+ value=+"true"+ />
  <property name=+"hibernate.connection.release_mode"+ value=+"after_statement"+ />
  <property name=+"hibernate.transaction.factory_class"+
  value=+"org.hibernate.transaction.JTATransactionFactory"+ />
  <property name=+"hibernate.transaction.manager_lookup_class"+
  value=+"org.hibernate.transaction.WeblogicTransactionManagerLookup"+ /> 
  <property name=+"hibernate.current_session_context_class"+
  value=+"org.hibernate.context.JTASessionContext"+ />
  <property name=+"hibernate.transaction.auto_close_session"+
  value=+"false"+ />

  </properties>

and the code (where we maybe need to do something to setup JTA Manager)



    EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.session");
    Environment env = KnowledgeBaseFactory.newEnvironment();
    env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);

    DO WE NEED THE LINE BELOW? I what shall it conatin in a Weblogic 10.3 EJB 3.0 environment?
     //env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());


Any hint and examples wold be very helpful!
