bonjour tout le monde , j utilise HibernateSynchronizer-3.1.9
j ai un probleme avec l ouverture de la session hibernate
ma console
Citation:
at model.dao._BaseRootDAO.closeSession(_BaseRootDAO.java:191)
at model.dao._BaseRootDAO.findAll(_BaseRootDAO.java:243)
at TransfertAtlantiqueServicePersistance.findAll(TransfertAtlantiqueServicePersistance.java:30)
at TransfertDeDonneesAtlantique.<init>(TransfertDeDonneesAtlantique.java:18)
at TransfertDeDonneesAtlantique.main(TransfertDeDonneesAtlantique.java:41)

comme plusieurs ont pu le remarque. C est le code généré par
HibernateSynchronizer.
Alors comment faire appel a mon configuration que je pense est mon hibernate.cfg.xml merci d avance
