Erreur d'utilisation Hibernate 3.5.1-Final avec Maven

Bonjour à tous,

Je rencontre deux problèmes qui sont peut être lié, je dois créer un projet en J2E et je me suis réorienté sur ces frameworks suivants: Hibernate, Spring et JSF
J'utilise également maven pour builder mon projet.
Je n'utilise que des annotations que ça soit pour hibernate et Spring.

Lorsque je deplois mon projet sous jboss 4.2.3.GA j'ai ce message d'erreur:

Je rappelle également que j'ai ce même erreur sous jboss 5.1.0.GA et sous glassfish.
Ca vient donc de la configuration de mon projet.

Le fichier applicationContext.xml se trouve à cette adresse:
http://code.google.com/p/gm3/source/...ionContext.xml

web.xml:
http://code.google.com/p/gm3/source/...EB-INF/web.xml

Et j'utilise un fichier *-DS.xml:
http://code.google.com/p/gm3/source/...ces/gm3-ds.xml

Et mon fichier pom.xml:
http://code.google.com/p/gm3/source/...nk/gm3/pom.xml

N'y a t-il pas une incompatibilité de la version de Hibernate?

Et mon deuxième problème est que je n'arrive pas à supprimer ou modifier une entité via une DAO mais j'arrive à ajouter :s

Enfin bref.. Merci de votre attention :)
Bonne journée,
