     Session session = HibernateUtil.getSessionFactory().getCurrentSession();
     session.beginTransaction();
     Query query= session.createQuery("select a.courseName  from Semester e inner join e.course as a"); 
   for (Iterator it = query.iterate(); it.hasNext();) {
       Object  row = (Object) it.next();
      combocourse.addItem(row);
     System.out.println(row);

     }        
       session.close();
   }
