En faite, si j'ai bien compris l'objet upFile est null alors que _name est bien mise a jour....
Je ne trouve pas de piste... surtout que dans l'exemple ça fonctionne.

Merci d'avance.

**snipes** · 27/03/2009, 15h26

apparement cette erreur signifie que tu es limité par la mémoire allouée à la JVM

t'as testé avec un petit fichier .txt (en supposant que ca vienne de la

)

**Elwe31** · 27/03/2009, 16h04

J'ai fait un petit fichier test.txt contenant "test".
Et j'ai le meme message... Java heap space

Par contre, le upload d'image de 5Mo fonctionne parfaitement bien dans le site exemple de tomahank que j'ai installé sur mon serveur.

Merci pour les reponses

**Elwe31** · 27/03/2009, 16h55

En bidouillant le fichier web.xml
Maitenant, j'ai ça dans le fichier localhost du serveur :
