Bonjour tout le ti monde,

Ce que je voudrais faire :
=>Je voudrais simplement lire un fichier XML et l'afficher dans ma console

Actuellement, j'ai dans ma console : "java.lang.UnsupportedOperationException: XStreamMarshaller does not support unmarshalling using SAX XMLReaders".

=> Je ne vois pas ce qu'il manque où peut se situer le problème ???

Ci-dessous les sources ...

Merci pour votre aide !!!
