[EJB 3.1] Log4J dans un EJB
Bonjour à tous,
Je voudrais créer un ejb (mon premier :):?) qui me log des informations sur mon serveur. Je voudrais utiliser l'API Log4J. Je travaille sur éclipse, j'ai donc créer un "Entreprise Application Projet".
Voici la code du Session Bean:

logger.info("logger initialized with " + LOG4J_XML + "...");
}
public void shutdown(){
logger.info("logger initialized with "+ LOG4J_XML + " shutdown");

Ce code est inspiré de ce blog
Mon problème est que lorsque je lance mon serveur, mon EJB démarre, mais j'ai une erreur

Tout d'abord, je tiens à signaler que je n'ai pas du tout la même architecture que celle présenté dans le blog; Ensuite j'ai essayé de changer plusieurs fois le path du fichier ou alors de déplacer le fichier dans différents répertoires (META-INF par exemple) mais sans succès.
Pouvez vous me dire d'où vient mon erreur?
Merci d'avance
