      Source of the called function

      public int createStatus(StatusAdapter adapter) {

      Query query = em.createQuery("SELECT OBJECT(s) FROM Status s WHERE s.name=?1")
      .setParameter(1, adapter.getName())
      .setMaxResults(1);
      if (query.getResultList().size()>0) return JBFinals.STATUS_NAM_ERR;

      Status status = new Status();
      status.setName(adapter.getName());
      em.persist(status);
      adapter.setId(status.getId());
      return JBFinals.PERSIST_OK;
      }


      Configuration in the persistence.xml file

      ...



      <!--create-drop--><!--org.hibernate.dialect.MySQLDialect-->


      </entity-manager>


      It is quite urgent to solve the problem and we have no idea.
