            query.setParameter(":userName", login.getUserName());
            query.setParameter(":password", login.getPassword());
            List result = query.list();

            System.out.println("resultset:"+result);

            while(iterator.hasNext()){
                userId = (int) iterator.next();


        }
    } catch (HibernateException e) {
        if (session.getTransaction() != …
