Exception étrange : This parser does not support specification "null" version "null"
Salut à tous :)
J'ai développé une application web avec spring grâce à maven et j'ai un problème
Le contexte
- Un application web utilisant springWebMVC
- Cette application utilise un module Jar
- Ce module Jar utilise DOM4J avec XPATH via Jaxen 1.1.1
Le déploiement de l'application sur GlassFish 3.0.1 fonctionne très bien
La problématique :
Lorsque je tente d'effectuer une action sur mon application j'obtiens toujours l'erreur suivante :

Manque une libraire.. mais laquelle ?

Lorsque je test toute ma librairie (utilisant cette méthode) tout passe
Mais lorsque je tente d'exécuter une action spring, l'exception mentionnée survient!
Ce que j'ai trouvé sur notre ami:Ceci
Solutions ?
Je ne sais pas :(
éclairez moi SVP !:D
Merci!
