probleme de connexion base de donnée HibernateRésolu

Question

je suis en train de devellopper une webapp et j'ai un probleme grave que je n'arrive pas &#224; resoudre, mon porgramme se connecte une fois sur deux &#224; la base et je ne comprend pas exactement ou c'est l'erreur.

pour de plus de clart&#233; j'ai mis ici la console d'eclipse tu resultat:
essai1: il ne recupere pas les resultat
essai2: OK

console:

Salut,

le classcastexception est pas normal. Tu as bien d&#233;fini le type de tes objets dans la config d'hibernate ? Et tes object respectent bien ce que tu as d&#233;fini ?
