Plusieurs upload dans une seule page jsp .
Bonjour à tous,
J'aimerais faire un upload de plusieurs pièces jointes, j’ai essayé avec une seule pièce jointe et ça marche .
Maintenant quand il s’agit de plusieurs boutons upload et plusieurs boutons parcourir ça veut pas marcher, je n'utilise pas les richefaces mais seulement le tomahawk-1.1.8, car j'ai pas beaucoup de temps pour apprendre le truc des richesfaces et c'est un peut compliqué pour configurer son projet, d’autre part j'utilise jsf RI 1.1.0.1 .
Finalement voila les fichiers de mon projet .
