[RichFaces] Problème avec FileUpload

**AllanRidley** · 16/07/2011, 09h49

Bonjour à tous,
j'essaie de réaliser une petite application web en utilisant pour la première fois JSF+Richfaces et des Java beans de Spring mais j'ai pas encore des notions claires sur le sujet. Là j'aurai souhaité permettre l'upload de fichiers. J'pensais notamment à de petits fichiers texte(.txt). Mais pour ce faire j'voulais réaliser un exemple simple et j'ai donc trouvé l'exemple de "live demo" Mais je n'arrive pas à le faire fonctionner

En fait j'ai voulu bidouiller les fichiers de configuration (avec un succès totalement absent) et j'obtiens le déploiement sur Tomcat et l'affichage de la page mais lorsque j'effectue le choix du fichier, le chemin d'accès pris est erroné ("fakepath" s'insère toujours puis il termine quand même par le nom correct du fichier) puis l'upload échoue.

J'ai la JSP suivante:

Si quelqu'un l'a déjà utilisé et pouvait avoir la bonté de me passer le contenu adéquat des fichiers de configuration XML à y ajouter pour que ça fonctionne ça m'aiderait beaucoup

Tu as un NPE à la ligne 50 de FileUploadBean. Ca correspond à quelle ligne exactement dans ton code ?

**AllanRidley** · 16/07/2011, 17h18

Désolé, j'ai fait une p'tite erreur, j'ai pas fourni le code exécuté lors de cet essai là.J'avais modifié FileUploadBean de la manière suivante en utilisant plutôt les annotations, vu que j'avais pas de résultat avec le 1er modèle:

Donc la ligne 50 c'est: "file.setLength(item.getData().length);" dans la méthode "public void listener(UploadEvent event)"

**Shinzul** · 16/07/2011, 17h45

A partir de la on peut penser que c'est le item ou le getData qui vaut null

.
Donc que ton item uploadé est bancal dans les deux cas.

A partir du code que tu as donné je voie pas où est l'erreur mais c'est surtout l'ajout du "fakepath" dans le chemin d'accès au fichier qui me perturbe. ET ce qui pourrait aussi être la cause d'un upload d'un fichier bancal.

Tu as modifié quoi dans la configuration pour que ca se déploie ?

**AllanRidley** · 16/07/2011, 18h05

Tel que le code a été conçu il devrait upload des images (jpg, png...) donc je ne test qu'avec des fichiers de ce type localisés à la racine de ma partition principale et d'autres dans un dossier de cette même partition. Ces fichiers s'ouvrent normalement en dehors des essais.
Pour les configurations j'ai le web.xml:

J'me disais que j'devais avoir manqué un truc important dans l'un de ces 3 fichiers vu que je n'ai pas réussi à trouver une configuration type pouvant s'accorder avec l'exemple de "live demo"

Le fait d'avoir mis l'environnement de développement sur une machine virtuelle par VMware Workstation peut-il avoir une influence sur la justesse du chemin d'accès des fichiers que l'on souhaite charger?

**Shinzul** · 19/07/2011, 15h13

Je voie pas trop l'erreur personnellement, a première vu je te dirai d'essayer de passer en scope Session pour voir si ce n'est pas lié à un problème de scope entre tes beans Spring et le scope attendu par le composant de RichFaces.
