J'ai erreur avec le vecteur ne peut pas lancer à IUser je ne sais pas pourquoi il erreur? j'ai été créer 1 classe pour convertir IUser mais pourquoi l'erreur? mais quand je change query.getResultlist() en ==> query.getSingleResult(); ça marche bien pourquoi ??? (Maintenant je pas encore vérifier la connexion utilisateur ou pas essayer simplement créer la page de connexion)
remerciez votre suggestion: D – Kency
