Bonjour,

Si je ne me prempe pas, il me semble qu'il y'a un probléme avec ton bouton;

Code:

<p><h:commandButton value="Inscription" action="register" /></p>

A mon avis, la valeur action d'un commanButton est

Code:

<p><h:commandButton value="Inscription" action="#{TonAction.MethodeInsertion}" /></p>

.

Pour cela, il faut avoir une classe java qui comportera ta méthode MethodeInsertion.
ça reste un avis. je te conseille de voir ce lien http://adiguba.developpez.com/tutoriels/j2ee/jsp/el/

Bon courage avec JSF.

Le problème avec la plupart des developpeurs , y compris (moi :mrgreen:) c'est qu'on ne lit pas assez ou pas du tout avant d'attaquer les nouvelles technos, pourtant on gagne du temps avoir lu. Prends du temps et lis ce tuto
