Bonjour,

Dans le cadre d'un projet de fin d'études, je suis en train de préparer ma couche d'accès aux données avec Hibernate. Puisque c'est une 1ere pour moi laors j'ai suivi le tutoriel "Débuter avec Hibernate sous Eclipse" de "Minosis" ave Hibernate Synchronizer.

Dans ce tutoriel, il est fortement conseillé de changer le code généré automatiquement par H.Synchronizer par un code qui est plus conforme à la documentation de Hibernate, c'est ce que j'ai fait..

Je vous poste mon fichier .hbm :

Utilisateur.hbm.xml
