Problème avec JSF + Hibernate + sous netbeans 7.0.1

**chniter** · 27/11/2011, 18h50

salut
Je suis entrain de développer une application web sous netbeans 7.0.1.
J'utilise hibernate et JSF.
Pour hibernate j'utilise les annotations (pas de fichiers hbm).
Ma base de données contient une seule table "Entreprise".
Mon projet:

hibernate.cfg.xml:

Code :
