    Jbpm integration transaction problem

    Eliseu Cartaxo Newbie

      Jbpm 4
      Jboss AS 5.0.0GA
      Oracle Database 10G


      I'm integration my application with jbpm using the example from the dev-guide

      this.processEngine = (ProcessEngine) ctx
       .lookup("java:/ProcessEngine");


      The jbpm-oracle-ds
