Je ne comprends pas car mon bean marche très bien si au lieu de lire le fichier je lui donne une valeur par ex : name="toto", il m'affiche bien toto.
Je me suis d'ailleurs assurer que mon fichier eétait accessible, j'arrive à le lire au même endroit.

Si quelqu'un peut m'éclairer sur ce mystère.
Merci d'avance
