bonjour,j'ai une methode de recherche suivant:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
 
public Employe getUser(String login) {
		// TODO Auto-generated method stub
		 Query query = em.createNamedQuery("Employe.findByLogin");
	        query.setParameter("login",login);
	        Employe user = (Employe) query.getSingleResult();
	        return user;
	}

si le login rechercher existe donc c'est bon pas d'erreuuur sinon voila l'erreur generer :
