    jBPM3, Seam 2.2 and Hibernate

    Sand Lee Newbie

      Hello,
      I have problems setting up jBPM with Seam and Hibernate. I followed the instructions of Seam in Action (Chapter 14) and as we configure Hibernate with annotations, we made jBPM aware of our Entities as described in JBPM-832.


      My problem is, that jBPM persists my entities still as bytearray.


      jbpm.cfg.xml


      <jbpm-configuration>
      
        <jbpm-context>
          <service name="persistence">
             <factory>
                <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
                   <field name="isTransactionEnabled"><false/></field>
                </bean>
             </factory>
          </service>
          <service name="tx" factory="org.jbpm.tx.TxServiceFactory" />
          <service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory" />
          <service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory" />
          <service name="logging" factory="org.jbpm.logging.db.DbLoggingServiceFactory" />
          <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory" />
        </jbpm-context>
      
      </jbpm-configuration>

        </session-factory>
      </hibernate-configuration>




      And I subclassed org.jboss.seam.bpm.Jbpm to add


      AnnotationConfiguration configuration = new AnnotationConfiguration();
      configuration.configure(); // reads hibernate.cfg.xml
      configuration.addAnnotatedClass(Enties.class); // .......
      
      PersistenceServiceFactory psf = JbpmConfiguration.getInstance().getServiceFactory(Services.SERVICENAME_PERSISTENCE);
      psf.setConfiguration(configuration);



      and enabled the component.


      Has someone an idea what goes wrong?
