Probleme de suppression

Salut a tous,
je dispose d' une table Composant, et une table Proprietes.
La table Propriete a pour chaque tuple une FK vers un Composant (logique).

Dans mon appli. java je me retrouve donc avec un set de Proprietes pour le Composant.

Tout fonctionne nickel pour le SELECT mais je veux DELETE certains Composants et donc leurs Proprietes.

Voilà comment je fais:

Code :

public static void supprimeSauvegarde(String save) throws HibernateException {
        Session session = HibernateUtil.currentSession();
        session.beginTransaction();
        List<Composant> results = session.createQuery("from Composant WHERE sauvegarde ='"+save+"'").list();
        for (Composant c : results) {
            for (Object o : c.getProprietes())
                session.delete(o);
            session.delete(c);
        }
        session.getTransaction().commit();
    }

En gros, je select tous les composants dont j' ai besoin, je supprime les proprietes de celui ci et ensuite le composant.

Mais une erreur se passe au moment du : commit();
