    org.hibernate.hql.ast.QuerySyntaxException: MyEntity is not

    Olaf Krause Newbie

      Hello,

      the application i write is deployed to the JBoss 4.0.3SP1 successfully. My client successfully calls simple session beans remotely.

      If the server side code tries to read or write an Entity, the appended exception is being thrown.

      The hot code is (please refer to the last line of each snippet):

      Query query = manager.createQuery(
       "SELECT ps FROM ProzessStatus AS ps "
       + "WHERE ps.applikation=:app AND ps.userId=:uid");
      query.setParameter("app", applikation);
      query.setParameter("uid", userId);
      
      ProzessStatus prozessStatus = (ProzessStatus)query.getSingleResult();
      


      and

       prozessStatus = new ProzessStatus();
       prozessStatus.setApplikation(applikation);
       prozessStatus.setUserId(userId);
       manager.persist(prozessStatus);
      


      After some debugging the exception now is catched and logged by the server side code as follows:
      19:36:50,008 ERROR [ProzessStatusServiceBean] java.lang.IllegalArgumentException: Unknown entity: org.mywms.deckerwms.model.ProzessStatus

      I do not believe in an unknown Entity, because the server logs says:

      19:34:12,898 INFO [Ejb3Configuration] found EJB3 Entity bean: org.mywms.deckerwms.model.ProzessStatus



      Another thing is, that if the application is undeployed, the server log tells me:


      19:50:50,622 WARN [Ejb3Module] Stopping failed jboss.j2ee:service=EJB3,module=DeckerWMS.ejb3
      javax.naming.NameNotFoundException: DeckerWMS not bound



      I have another project here, which seems to work properly with equal settings and configurations.
      I have checked everything up and down several times; without success.

      Please - please help!
