[Hibernate 3/ Tomcat 5.5] Problème de connexion à la base de données

Bonjour à tous,

Voilà, je me lance dans le développement J2EE et plus précisément des
Servlet et JSP. Je souhaite assurer le mapping de mes données en utilisant
Hibernate. Si j'effectue un essai de connexion direct avec une JSP et JSTL
(sans passer par Hibernate) cela fonctionne parfaitement. Par contre une
fois que j'essaye avec une servlet et Hibernate tout casse et je comprends
pas pourquoi.

Je vous remercie d'avance pour les avis éclairés et l'aide que vous
m'apporterez.

Bernard

Voici, mon descripteur de Context :
