Salut a vous tous
je débute le développement sous eclipse avec Hibernate et je rencontre un problème d'exécution de mon programme

Ma configuation :
- La SDK Eclipse (3.2.0)
- Hibernate3
- Tomcat 5.5

Mon fichier hibernate.cfg.xml

Code :

Il n'affiche donc aucune erreur mais lorsqu'il passe dans ma classe ifl tente d'exécuter la commande SessionFactory factory = new Configuration().configure().buildSessionFactory(); mais il passe ensuite directement sur le finally (j'ai fait les tests en mode pas à pas)

Je ne vois pas où est le problème (je précise que j'ai cherché sur les forums et sur l'ensemble des ressources mis à notre disposition)

Pouvez-vous m'aider ?
