Bonjour,

ça fait un moment que j'essaye de faire tourner Myfaces sur eclipse...j'ai ce message d'erreur :

Quelle version de tomcat?

[Elwe]

Tomcat 7.

[tchize_]

Tomcat 7 inclue déjà une implémentation JSF (et je pense que c'est myfaces), tu ne dois donc PAS inclure de librairie JSF dans ton projet eclipse. Ce message d'erreur laisse sous entendre que tu as inclu ta propre version de myfaces à ton projet et qu'il entre en conflit avec celui de tomcat.

[Elwe]

Ok, merci beaucoup

j'ai donc viré les librairies myface de mon projet.
J'ai maintenant :

[tchize_]

ca c'est ennuyeux, car ce qu'il faut c'est justement l'exception en question pour savoir où est le problème

tu peux mettre le log complet de ton tomcat?
