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'

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!
