Est ce que qqun peut m'expliquer pourquoi il en veut pas de mon fichier de mapping ?
J'ai peut etre une piste mais franchement je comprend pas , en gros la ligne de code du fichier Eventmanager.java
HibernateUtil.getSessionFactory().close();
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
me sort une erreur ( sous eclipse souligné de rouge ) : HibernateUtil ne peut etre resolu
et
Event theEvent = new Event(); n'est pas reconnu comme type valide.
Voila la ça me depasse sachant que mon arborescence c'est :
src -- events -- Event.java
Event.hbm.xml
Eventmanager.java ( class main d'execution )
-- util -- HibernateUtil.java
Hibernate.cfg.xml
Merci à vous d'avance
