Problème de lecture du fichier de mapping
Bonjour,
Je débute tout juste avec Hibernate. Je suis donc allé sur le site hibernate.org où j'ai téléchagré la version 3.1 de Hibernate. J'ai suivi les instructions de ce tutoriel http://www.hibernate.org/hib_docs/v3.../tutorial.html.
Je suis donc arrivé jusqu'à la partie 1.2.6 . J'ai donc l'arborescence suivante pour mon projet de test :

La compilation se passe bien. Le problème vient apparemment du fichier de mapping Event.hbm.xml qu'il n'arrive pas à lire. Pourtant le chemin d'accès est bon je pense.
Quelqu'un pourrait aurait il une idée plus précise d'où le problème peut venir ?
Merci d'avance de votre aide.
