        Transaction txUpdate = sess.beginTransaction();        Query update=sess.createQuery("update ProjectSummary ps set ps.bean3dot1 = :bean3dot1 where ps.id = :id")            .setEntity("bean3dot1", bean3dot1)            .setInteger("id", (Integer) session.get("ID"));        update.executeUpdate();        txUpdate.commit();
