Bonjour,
J'ai voulu essayer l'exemple tree de tomahawak fourni dans le site de tomahawk mais le serveur tomcat 7 a rencontré des problèmes:

Librairies utilisées:

Tomahawk20-1.1.10
JSF mojarra-2.1.2-FCS

pouvez vous m'indiquer la source de cette erreur ??
merci d'avance

Euh comme ca, après je suis pas un expert en configuration de projet ^^

Ton projet ne trouve pas la classe org.apache.myfaces.custom.tree.MutableTreeNode, ce qui me semble plutot logique vu que ton implementation de JSF est mojarra.

alors je dois utiliser quelle implémentation ?
