hibernate problem (classe not mapped)

:cry:
il parai que jai pas de chance avec hibernate, une fois que je dit que jai resolu un probleme une autre apparai (mais ce pas grav, c avec les problemes qu'on apprend:D ),
jai une base de données dans la quelle il y a des relation entre les tables ce qui implique avant de supprimer une ligne de la table (table maitre)je dois supprimer ses instances dans les autres tables ( tables esclave) tout ca pour une meilleure gestion de mon application.mais le probleme c'est que quand j'instancie dans la classe maitre un objet de la classe esclave generés par hibernate me donne une exception de type: 'ma classe' not mapped
plz si qlq 1 a une idée,tutorial ou un link te merci pour votre aide

Bein faut la mapper.

Donne nous ton fichier de conf hibernate et tes fichiers de mapping correspondant.

@+

pour que ca soit plus clair je vais vous dire en detail mon problem.

j'utilise myeclipse dont hibernateb qui genere automatiquement les classes et les fichiers de configuration, mon travail consiste seulement dans la configuration.

en fait le probleme ne consiste pas dans le fait que hibernate genere tous car mon application tourne dans des limites.

ce que jai fai dans mon application est comme suit:
jai deux table dans ma base de données
group{idGroup,desc.....}
user{iduser,lastname,...,idGroup}

la cle de la table group migre vers la table user, et tous ca cest normal.
apres la generation des classes correspondantes et tous les fichiers necissaire
par hibernate jai cree une classe 'ManageGroups' qui administre les groupes et une autres Manageusers qui administre les users,
pour etre indipendant de la base de données et indipendant de l'utilisation des triggers ;
pour ca jai fait dans 'ManageGroup' dans la methode qui supprime un group ,avant de supprimer un group de parcourir toute la table user et de supprimer tous les users qui appartiennent à ce group.

mais ce que je ne comprend pas est que je manipule les users parfaitement avec les manipulations possible (ajout, modification ,
consultation) ce qui preuve que le mappage de la classe User s'est bien fait mais quand j'instancie une objet de type User dans la classe ManageGroup ca na marche pas.
merci pour votre aide d'avance et si qlq un à une idée j'aimerai bien connaitre comment resoudre mon probleme

Donne nous le code de tes classes.

pour le fichier xml de configuration :

quand j'instancie une objet de type User dans la classe ManageGroup ca na marche pas

Code de ManageGroup ?

ici le morceau qui supprime tous les users par un group:

Citation:

---

protected void deleteUsersByGroup( Integer idGroup) throws HibernateException{
List users = getUsers();
for (int i = 0; i < users.size(); i++) {
Users user = (Users) users.get(i);
Groups group=user.getGroups();
if ( group.getIdGroup()== idGroup) {
deleteUser(user.getIdUser());
}
}
}

---

et ici la suppression du groups:

Citation:

---

public void deleteGroup(Integer idGroup)throws HibernateException
{
/**Avant de supprimer un Group, il faut supprimer les Users associés**/
ManageUsers manageUsers=new ManageUsers();
manageUsers.deleteUsersByGroup(idGroup);
/**Suppression de Group**/

Groups group=new Groups();

group.setIdGroup(idGroup);

Session session = HibernateSessionFactory.currentSession();
Transaction tx = session.beginTransaction();
session.delete(group);
tx.commit();
HibernateSessionFactory.closeSession();
}

---

A supprimer
