Probleme de mapping avec Hibernate
Bonjour tout le monde!!
Je suis un debutant concernant l'utilisation de hibernate.
je signale que je travaille avec Hibernate 3.0
jé appliqué tout ce que jé trouvé ds un tutoriel mé ça n 'a pas marché.
voila ce que jé fé :

Mé il me donne les erreurs suivants :
Citation:
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Erreur Mapping
sachant que jé ajouté deja le log4j.jar.
