    M:M relation in latest JBoss

    Erik Turesson Novice

      Hello!

      I have two entity beans, User and AccessGroup.
      An User can be member of many AccessGroups and an AccessGroup can have many Users. This worked fine for me with a JBoss build upon CVS in late May. However the same code does not work in the latest JBoss from CVS.
      When I try to assign an User to an Accessgroup nothing happens.

      The code that does that is below:

      /**
      * addUserToAccessGroup
      *
      * @ejb:interface-method view-type="remote"
      */
      public void addUserToAccessGroup(long accessGroup, long userId, long adminId)
      throws UserDoesntExistException, AccessGroupDoesntExistException, UserNotAuthorizedException{
      try{
      if(!isUserAuthroized(adminId)){
      ctx.setRollbackOnly();
      throw new UserNotAuthorizedException(adminId);
      }
      }catch(UserDoesntExistException e){
      ctx.setRollbackOnly();
      throw new UserNotAuthorizedException(adminId);
      }
      try{
      UserLocal user = getUserLocal(userId);
      AccessGroupLocal group = getAccessGroupLocal(accessGroup);
      Set users = group.getUsers();
      users.add(user);
      }
      catch(UserDoesntExistException e){
      ctx.setRollbackOnly();
      throw e;
      }
      catch(AccessGroupDoesntExistException e){
      ctx.setRollbackOnly();
      throw e;
      }
      }



      Below is examples om my ejb-jar.xml file and I since I dont manage to attach the Bean implementations I include them to. The ejb-jar.xml file is generated using XDoclet. I do not use the jbosscmp-jdbc.xml file generated since it contains errors in the relation mapping. Do I have to use that file in the latest JBoss?
