Utilisation de EntityManagerFactory

Version imprimable

Bonjour,
Je viens de commencer un projet, j'ai créer un bean pour une interface d'inscription dans laquelle je doit récupérer des informations à partir de la base en utilisant les JpaController déja fournis, mais les problème s'avère lors de l'initialisation, en particulier avec EntityManagerFactory sachant que l'unité de persistance est configurée. Voici le code du bean:

Bonjour,
Peut on voir le code de la classe Ville?

Bonjour,
C'est bon pour cette exception j'ai modifié le code comme suit:

 try {
            utx = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
            System.out.println("user transaction created!");
        } catch (NamingException ex) {
            Logger.getLogger(NouveauPersonnel.class.getName()).log(Level.SEVERE, null, ex);
        }
 
        villeJpaController = new VilleJpaController(utx, Persistence.createEntityManagerFactory("smartwayPU"));
 
 
        villes = villeJpaController.findVilleEntities();

Mais maintenant dans la selectOneMenu j'ai un soucis pour le converter voici le code:

        return ((Ville) value).getCodePostal().toString();

L'exception est la suivante:

Code:

Grave: java.lang.ClassCastException: java.lang.String cannot be cast to com.smartway.entities.Ville

Merci pour votre aide d'avance

Ton erreur doit être là :
Code:

1 2 3 4 5 @Override public String getAsString(FacesContext context, UIComponent component, Object value) { return ((Ville) value).getCodePostal().toString(); }
Je pense que tu transmets un String à ton converter, en pensant envoyer un objet Ville. Mets un point d'arrêt dans cette méthode pour voir le type réel récu dans value.

exactement c'était le cas, je l'ai corrigé merci beaucoup, maintenant j'ai une nouvelle exception lors de l'execution.
dans faces-config.xml j'ai déclarer mon managedbean:

Code:
