@Override
	public List<Employee> listAll(int start, int step) {
//		Session s =  this.getHibernateTemplate().getSessionFactory().getCurrentSession();
		Session s =  this.getHibernateTemplate().getSessionFactory().openSession ();
//		System.out.println(s);
		Query q =s.createQuery("from Employee"); 
		q.setFirstResult(start); 
		q.setMaxResults(step); 
		List l = q.list(); 
		if(l != null)
			return l;
		else
			return null;
	}
