Answer 1

Try this and let me know if it works for you:

  // you should have the DAO class containing this queries 
  // extend HibernateDaoSupport

  List topList = getSession().createQuery("FROM Reviews r WHERE r.book = " 
          + book + " ORDER BY r.stars asc").setMaxResults(3).list();

  List bottomList = getSession().createQuery("FROM Reviews r WHERE r.book = " 
          + book + " ORDER BY r.stars desc").setMaxResults(3).list();
