try{
// This step will read hibernate.cfg.xml
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
session = sessionFactory.openSession();
model.xxxUtilisateur qu= new xxxUtilisateur();
qu.setLogin("admin");
System.out.println("L'utlisateur"+qu.getLogin()+"est crée");
