    RC9 mappedBy and InheritanceType.JOINED problem

    Jason Long Master

      I want to upgrade to JBoss 4.0.5, but I cannot deploy my applications anymore.

      I have some classes with

      @Inheritance(strategy=InheritanceType.JOINED )


      and a collection mapped as

       private Set<Coupling> couplings;
       @OneToMany(mappedBy="state")
       public Set<Coupling> getCouplings() { return couplings; }
       public void setCouplings(Set<Coupling> couplings) { this.couplings = couplings; }
      


      State is not a property of Coupling, but is a property of the base class GenericItem.

      This deployed find in 4.0.4, but now I get the following error. Is this due changes in RC9? I would appreciate any advice on a workaround or solution.

        • 1. Re: RC9 mappedBy and InheritanceType.JOINED problem
          Andrew Rubinger Master

          Does GenericItem have a @MappedSuperclass annotation? And does the "state" field or getter method have @ManyToOne?

          S,
          ALR

            Jason Long Master

            GenericItem does not have a @MappedSuperclass. Adding this gets me past that error, but I then get the error at the bottom of this post and breaks my application in 4.0.4.

            Did something change in the EJB3 spec that prevents me from using mappedBy on the property property of a superclass?

            The following code appears in my State class.

             private Set<Coupling> couplings = new HashSet<Coupling>();
             @OneToMany(mappedBy="state")
             public Set<Coupling> getCouplings() { return couplings; }
             public void setCouplings(Set<Coupling> couplings) { this.couplings = couplings; }


            GenericItem has the following and Coupling extends GenericItem


            private State state;
             @ManyToOne
             public State getState() { return this.state; }
             public void setState(State state) { this.state = state; }

            • 3. Re: RC9 mappedBy and InheritanceType.JOINED problem
              Jason Long Master

              I thought I was using RC9, because I used the 4.0.5 installer I just downloaded from

              http://labs.jboss.com/portal/jbossas/download

              I selected EJB3 profile. After investigating the manifest in

              jboss-4.0.4.GA\server\default\deploy\ejb3.deployer says RC8, but

              the one from the new installer found in

              jboss-4.0.5.GA\server\default\deploy\ejb3.deployer says RC7. See below.

              Manifest-Version: 1.0
              Ant-Version: Apache Ant 1.6.5
              Created-By: 1.5.0_09-b03 (Sun Microsystems Inc.)
              Specification-Title: JBoss EJB 3.0
              Specification-Version: JBoss EJB 3.0 RC7 - FD
              Specification-Vendor: JBoss
              Implementation-Title: JBoss EJB 3.0
              Implementation-URL: http://www.jboss.com/products/ejb3
              Implementation-Version: JBoss EJB 3.0 RC7 - FD
              Implementation-Vendor: JBoss
              


              I do not know if this has anything to do with my problem.

                Andrew Dale Newbie

                Hi Jason,

                I don't think the null pointer exception is caused by EJB RC9 but rather by Hibernate 3.2.0.GA that ships along with JBoss 4.0.5GA. To get it to work it will require you to manually patch the fromClause.java (very simple patch, only 1 or 2 lines). I have entered a bug in the Hibernate JIRA (http://opensource.atlassian.com/projects/hibernate/browse/HHH-2159), if you want it fixing, please vote for the issue.

                Cheers,


                Andy

                  I hit this bug as soon as I upgraded to 3.2

                  Caused by: java.lang.NullPointerException

                  This query started failing with NPE:

                  select _this.name, _this.language.name,
                  cast (_this.dateOrder as integer)
                  from Country _this
                  left outer join _this.language
                  


                  When I took out the cast, it worked, but that's not what I need.

                  select _this.name, _this.language.name,
                  _this.dateOrder
                  from Country _this
                  left outer join _this.language
                  


                  But if I gave the joined association an alias, it worked again:

                  select _this.name, l.name,
                  cast (_this.dateOrder as integer)
                  from Country _this
                  left outer join _this.language l
                  


                  It should be reproducible on your in-house test cases:

                  select _this.name, _this.mate.name,
                  cast(_this.weight as integer)
                  from cat _this
                  left outer join _this.mate
