J'ai modifier le projet pour en même temps utiliser maven2 comme gestionnaire de dépendances (apprend aussi à utiliser maven2).

Voici mon pom.xml (je n'ais pas les même librairies que le tutoriel)

Code :

Apparament c'est la formation du fichier qui n'est pas bonne : recognized obsolete hibernate namespace (je ne vois pas quoi changer).

Merci d'avance.

Il ne trouve pas la classe org.postgresql.Driver
Vérifie ton path
