JbossV5(EJB3) Eclipse

Bonjour,
SVP,j'ai un sérieux problème. je dois faire un site de location d'objets sur eclipse en utilisant EJB3 et la base de données de Jboss. J'ai tout installé. J'ai pris le programme EjbModule d'une amie(il ya les entités et les sessions).
Je l'ai lancé sous jboss et tout est clair,il n'y a aucune erreur et il construit bien les tableaux dans la base de données de Jboss. Pour mon site,j'ai aussi créé un projet avec mes entités et mes sessions exactement comme pour mon amie vu qu'on travaille meme dessus ensemble. Mais quand je lance jboss avec ce projet à l'interieur il m'affiche des erreur,pourtant le meme projet sur le pc de mon amie fonctionne,on retrouve la base de données avec les tableaux,pourtant quand c'est sur ma machine,il ne cree meme pas les tables,alors que comme dit précédement pour le projet de mon ami(qui traite autre chose) il fonctionne aussi bien chez moi.
Je dois remettre ce projet dans 2 semaines je ne sais comment faire. Si je ne reussis pas à remplir ma base de données je ne peux pas continuer mon projet,donc je vous prie de m'aider.Le plus tot serait le mieux.
Voici ce que Jboss affiche quand il se lance:
