Qu'est-ce que tu veux dire par "j'arrive pas a acceder aux objets typologieMission,client ,ect ", message d'erreur, stacktrace, ?

salut merci pour votre reponse.

je veux dire par "je n'arrive pas a y accéder" c'est quant j'instanciée un objet expérience professionnelle et que je fais par exemple un test

System.out.println("test" + listeExperiences.get(i).getPoste().getLibellePoste());
ca ne m'affiche rien et ca me donne la trace suivante

ce me l'affiche corectement.

Citation:

the owning Session was closed

Soit comme tu l'as fait, on met le lazy à false (attentions aux risque de charger en cascade tout la db pour récupérer un simple objet), soit on ne ferme pas la session hibbernate tant qu'on en a pas fini avec l'objet (méthode recommandée pour pouvoir utiliser le lazy loading et donc décharger un peu la mémoire)
