faces-config : déclaration bean par DenisDuval - page 1

Bonjour.

Dans une appli web en JEE et JSF, j'utilise 2 bean : aBean et bBean.

Je souhaite utiliser bBean à partir de aBean.

Le bean aBean :

package manager;

import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.ViewScoped;

@ViewScoped
@ManagedBean(name = "aBean")
public class ABean implements Serializable {

    @ManagedProperty("#{bBean}")
    private BBean bBean;
    
    private String libelle;

    public ABean() {
    }

    @PostConstruct
    public void init() {
        
        setLibelle(getbBean().getLibelle());
    }

Le bean bBean :

package manager;

import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ViewScoped
@ManagedBean(name = "bBean")
public class BBean implements Serializable {

    private String libelle;
    
    public BBean() {
    }

    @PostConstruct
    public void init() {
        
        setLibelle("Bonjour");
    }

Le fichier faces-config.xml :

<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
              xmlns="http://xmlns.jcp.org/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                                  http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">   
    <managed-bean>
        <managed-bean-name>aBean</managed-bean-name>
        <managed-bean-class>manager.ABean</managed-bean-class>
        <managed-bean-scope>view</managed-bean-scope>
    </managed-bean>
    
    <managed-bean>
        <managed-bean-name>bBean</managed-bean-name>
        <managed-bean-class>manager.BBean</managed-bean-class>
        <managed-bean-scope>view</managed-bean-scope>
    </managed-bean>
</faces-config>

Si je déclare les 2 bean dans le fichier faces-config, j'obtiens une erreur.

Je suppose que le fichier faces-config n'est pas correct.

Pouvez-vous m'aider SVP.

Merci.
