probleme avec GWT et Hibernate
Bonjour,
Je développe une web app en GWT. Gràce a hibernate j'ai généré mes objets persistant (j'utilise les annotations). J'ai une couche de DAO. Tous ça est coté serveur.
A l'aide de RPC je fais ceci :
Code:
1
2
3
4
5
6

public class AuthentificationServiceImpl extends RemoteServiceServlet implements
AuthentificationService {
public Boolean connect(String login, String password) {
AdminsDao adminDao = new AdminsDaoImpl();
return (Boolean)adminDao.checkLogin(login, password);
}
} |
Le code de AdminsDaoImpl:
Code:
1
2
3
4
5
6
7
8
9

public class AdminsDaoImpl implements AdminsDao{
@Override
public boolean checkLogin(String login, String password) {
if (null == login || null == password) {
throw new IllegalArgumentException("Login and password are mandatory. Null values are forbidden.");
}
Session session = HibernateUtil.currentSession();
// create a new criteria
Criteria crit = session.createCriteria(Admins.class);
crit.add(Restrictions.ilike("login", login));
crit.add(Restrictions.eq("pwd", password));
Admins admin = (Admins)crit.uniqueResult();
HibernateUtil.closeSession();
return (admin != null);
} |
et la parti création de la sessionFactory de HibernateUtil (j'ai l'impression de ça foire ici) :
Code:
1
2
3
4
5
6
7
8
9

|
static {
try {
// Crée la SessionFactory
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (HibernateException ex) {
throw new RuntimeException("Problème de configuration : "
+ ex.getMessage(), ex);
}
} |
Et il me donne cette erreur:
Code:
1

Avez-vous une idée du problème.
J'ai peut-être loupé un épisode pour l'intégration de hibernate, je n'ai fais qu'ajouter les jar au classpath...
Merci
