Salut
je développe une simple application web avec JSF sur netbeans 6.8.
Dans la page d'accueil il faut entrer le nom d'utilisateur et le mot de passe pour accéder à l'autre page web (si le d'utilisateur et mot de passe sont valide on accède à la page "welcomeJSF.jsp" sinon "error.jsp") le problème est que je n'arrive pas à accéder aux autres pages chaque fois que je clic sur le boutton"submit" une message d'erreur s'affiche, et je n'arrive pas à trouver l'erreur
SVP aidez moi je suis une débutante
voici le code source
user.jsp
