J'ai suivi exactement le tutoriel se trouvant dans la documentation d'hibernate (l'exemple avec les Events).
Et quand je veux lancer la premiere routine qui enregistre un premier Event , j'ai cette erreur que je ne comprends pas :
Code:

Je n'y comprends rien; je crois lire que c'est un probleme avec la librairie commons-logging mais je vois pas comment le resoudre.
Cela doit etre une erreur toute bete, mais aucun moyen de trouver la solution... pourriez vous m'aider s'il vous plait?
