[JSF / PrimeFaces / GlassFish] Bouton upload ne fonctionne pas

Bonjour,

je veux créer un bouton qui me permet d'uploader des fichiers dans un dossier( dans mon cas: c:\tmp).lorsque je clik sur "choose" pour uploader mon ficher, ce dernier s'affiche sur l'ecran avec une barre de progression du telechargement.mais une fois que je click sur le bouton upload mon fichier disparait de la page.xhtml et mon dossier (c:\tmp) est toujours vide.
je vais poster tout mon code en espérant que quelqu'un puisse m'aider.
