[خورشید *ستاره]

سلام من برای حذف کد زیر رو نوشتم ولی متاسفانه یه خطایی دارم کسی میتونه کمکم کنه؟؟

@Overridepublic void cancelTask(List<DeviceTask> deviceTasks) {

    String ids = "";

    for (DeviceTask deviceTask : deviceTasks) {

        ids += deviceTask.getId() + ",";

    }

    Session session = null;

    try {

        session = getSession();

        Transaction tx = (Transaction) session.beginTransaction();



        String hqlUpdate = "update DeviceTask dt set dt.done =true ,dt.taskStatus = 6 " +

                " where dt.activate =true and dt.done=false and dt.id in ("+ids+")";

        int updatedEntities = session.createQuery(hqlUpdate)

                .executeUpdate();

        tx.commit();

    } catch (RollbackException e) {

        e.printStackTrace();

    } catch (HeuristicMixedException e) {

        e.printStackTrace();

    } catch (HeuristicRollbackException e) {

        e.printStackTrace();

    } catch (SystemException e) {

        e.printStackTrace();

    } finally {

        session.close();

    }

}
