Quelqu'un aurait un petit idée d'où peut provenir mon erreur ?

Merci d'avance.

salut,
Dans ton fichier de mapping .hbm.xml tu as précisé le package="back.comptes" et en même temps tu as déclaré le nom complet de ta classe <class name="back.comptes.Comptes" ...>, je crois que c'est normal que hibernate ne s'y retrouve plus. Donc soit tu enlèves la déclaration package et tu conserves le nom complet de la classe, soit tu gardes la déclaration package et dans ce cas tu n'indiques que le nom court de la classe, c'est-à-dire juste Comptes.
Je pense que le problème vient de là.
