JSF 1.2 sur Websphere 7.0.0.9: propriété de grains de support non trouvé

Question

Je travaille sur JSF1.2 + EJB3.0 + Websphere 7.0.0.3. Toute la couche logique métier et couche de données (EJB 3.0) sont testés et fonctionnent avec succès depuis le début. Après j'ai intégré JSF1.2, je suis arrivé ces erreurs quand j'ai essayé d'obtenir des données de base de données:

E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Uncaught exception created in one of the service methods of the servlet Faces Servlet in application de.rwth.swc.ejb.generator.prototype.muster.ear. Exception created : javax.servlet.ServletException: /modelroot.jsp(19,5) '#{modelRootBean.getCustomers}' The class 'de.rwth.swc.ejb.generator.prototype.muster.client.backingbeans.ModelRootBean' does not have the property 'getCustomers'.

ModelRootBean (backingbean)

package de.rwth.swc.ejb.generator.prototype.muster.client.backingbeans;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import javax.ejb.EJB;

import de.rwth.swc.ejb.generator.prototype.muster.controller.ModelRootControllerBean;
import de.rwth.swc.ejb.generator.prototype.muster.domain.Contract;
import de.rwth.swc.ejb.generator.prototype.muster.domain.Customer;

public class ModelRootBean implements Serializable{

    private List<Customer> customers;
    private List<Contract> contracts;

    @EJB
    private ModelRootControllerBean modelRootControllerBean;

    public ModelRootBean()  {
        customers = new ArrayList<Customer>();
        contracts = new ArrayList<Contract>();
    }

    public List<Customer> getCustomers() {
        customers = modelRootControllerBean.getAllCustomer();
    }

    public void setCustomers(List<Customer> customers) {
        this.customers = customers;
    }

    public List<Contract> getContracts() {
        //contracts = modelRootControllerBean.getAllContracts();
        return contracts;
    }

    public void setContracts(List<Contract> contracts) {
        this.contracts = contracts;
    }
}

Je suis tout à fait sûr que cette erreur pourrait venir de mon erreur stupide, mais je ne pouvais pas comprendre. aider quelqu'un peut me sortir?

Answer 1

Il suffit de remplacer

value="#{modelRootBean.getCustomers}"

avec

value="#{modelRootBean.customers}"

Answer 2

Utiliser modelRootBean.customers au lieu de modelRootBean.getCustomers.

propriétés ManagedBean doivent être appelés sans préfixe "get" dans jsf.
