    Some warnings after entity persist

    Nick Gochiashvili Newbie

      Dear All,

       

      I am getting WARNING after I am  saving the entity -  witch has  Hibernate UserType as one of the fileds.  (see warning below).

       

      Persist and saving operations being performed successfully, but after that I am always getting warning mentioned above.

       

      Please see source code and warning below.

       

      Is this warning something important? Can I  ignore  it?

       

       


      Preconditiopns: JBoss 7.1.1.Final


      • UserType column is used in Hibernate.

        Source Code:


      public class MyUserType implements UserType {

      @Override

      public int[] sqlTypes() {

      return new int[] { Types.BIGINT };

      }

      @Override

      public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor session,           Object owner) throws HibernateException, SQLException {

      Object param = LongType.INSTANCE.nullSafeGet(rs, names, session, owner);

      return param;

      }

      @Override

      public void nullSafeSet(PreparedStatement st, Object value, int index,                     SessionImplementor session) throws HibernateException, SQLException {

      long param = 0;

      // Remote EJB Inject and load param

      LongType.INSTANCE.nullSafeSet(st, param, index, session);

       

      }

       

      ...

       

       


      }

       

       

       

       

       

      • UserType is defined in  Entity in following way:  

       


      @Entity(name = "MY_ENTITY")

       

      public class MyEntity implements Serializable {

       

      @Type(type = "MyUserType")

      private Object myType;

      }

      •  

      • Problem being occurred in following code:  

         

        @Local(MyLocal.class)

      @Stateless

      public class MyEjb implements MyLocal {

      @PersistenceContext

      private EntityManager em;

       

      @Override

      public MyEntity save(MyEntity myEntity) {

      em.persist(myEntity);

      return myEntity;

      }

      }

       

       

      See stacktrace below:
