Bonjour,
Si je ne me prempe pas, il me semble qu'il y'a un probléme avec ton bouton;
<p><h:commandButton value="Inscription" action="register" /></p>
A mon avis, la valeur action d'un commanButton est
<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.
