I beg for help here.
I already tried everything and could not make it work.
I'm calling a PROCEDURE, which returns a refcursor. My code executes perfectly, however the ScrollableCursor is with the result set closed and I can not find out why or how to do otherwise.
Please help me person. This is very difficult
My Error:
Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.4.2.v20130514-5956486): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Result set already closed
EntityManagerFactory createEntityManagerFactory = Persistence.createEntityManagerFactory("localFactPU");
//EntityManager em = FJPAManager.getInstance().getEntityManagerContext("localFactPU").getEntityManager();
EntityManager em = createEntityManagerFactory.createEntityManager();
em.getTransaction().begin();
em.getTransaction().isActive();
System.out.println(em.isOpen());
//em.getTransaction().begin();
ReadAllQuery databaseQuery = new ReadAllQuery(DBAJobsOracleEntity.class);
databaseQuery.useCursoredStream();
StoredProcedureCall calles = new StoredProcedureCall();
calles.setProcedureName("FAC_JOB_INTEGRATION.TEST_ESTEVAO");
calles.useNamedCursorOutputAsResultSet("JOBS_PARAM");
databaseQuery.setCall(calles);
databaseQuery.useCursoredStream();
databaseQuery.useScrollableCursor(1000);
//session = ((JpaEntityManager) getEntityManager().getDelegate()).getActiveSession();
//session.executeQuery(databaseQuery);
//JpaQuery queryess = (JpaQuery) ((JpaEntityManager)getEntityManager().getDelegate()).createQuery(databaseQuery);
JpaQuery queryess = (JpaQuery) ((JpaEntityManager)em.getDelegate()).createQuery(databaseQuery);
queryess.setHint(QueryHints.CURSOR, true);
queryess.setHint(QueryHints.CURSOR_INITIAL_SIZE, 2);
queryess.setHint(QueryHints.CURSOR_PAGE_SIZE, 5);
queryess.setHint(QueryHints.RESULT_SET_CONCURRENCY, ResultSetConcurrency.ReadOnly);
String resultSetType = ResultSetType.DEFAULT;
queryess.setHint(QueryHints.RESULT_SET_TYPE, resultSetType);
ScrollableCursor scrollableCursor = (ScrollableCursor)queryess.getResultCursor();
DatabaseSessionImpl databaseSession = ((JpaEntityManager)em.getDelegate()).getDatabaseSession();
scrollableCursor.setSession(databaseSession);
scrollableCursor.next();
scrollableCursor.close(); |
