[Hibernate] Erreur de configuration ?
Bonjour j'essaye de faire fonctionner ce petit bout de code :
Code:
1 2 3 4 5 6 7 8 9
|
Session session= HibernateUtil.getSessionFactory().getCurrentSession();
Transaction tx = session.beginTransaction();
UserDTO user = new UserDTO();
user.setUserName("greg");
user.setPassword("greg2");
session.save(user);
tx.commit(); |
Mais j'ai une erreur du type :
Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

} catch (Throwable ex) {

System.err.println("Initial SessionFactory creation failed." + ex);
ex.printStackTrace();
throw new ExceptionInInitializerError(ex);
}
}
