Managed bean

Hello folks

I have this JavaBean :

package controller;
import beans.Association;
import beans.Personne;
import java.io.Serializable;
import model.Model;
import model.SimpleModel;
import views.ListView;
import views.View;

public class AssociationListController implements Controller, Serializable {

private Model model;
	private View view;
	private Personne personne;

public void setModel(Model model) {
                this.model = model;
            }

public void setPersonne(Personne personne) {
                this.personne = personne;
            }

public void setView(View view) {
                this.view = view;
            }

public Personne getPersonne() {
                return personne;
            }

public Model getModel() {
                return this.model;
            }

public View getView() {
                return this.view;
            }
            //Constructeur
            public AssociationListController() {
               this.personne = new Personne();
               this.model = new SimpleModel();
               this.view = new ListView();
               this.model.setDatas(new Association());
            }

public void removeSelectedPersonnes(){
		System.out.println("suppression d'une personne..");
		Association assoc =(Association) getModel().getDatas();
		assoc.getAdherents().removeAll(getView().getSelectedObjects());
	}

public void addPersonne() {
		System.out.println("insertion d'une nouvelle personne..");
		Association assoc = (Association)getModel().getDatas();
		assoc.getAdherents().add(this.personne);
		System.out.println("Adhérents : "+assoc.getAdherents());
        }
     }

and this jsp page:

and this is my faces-config.xml

I have this exception while trying to access my Javabean with that JSP :

Can you helop please?

You capitalized the package name ("Controller") in your faces-config file. Java is case-sensitive and package names should never contain upper-case letters.

Incidentally, a backing bean is not a Controller. Although it can contain some controller functions, it's primarily a Model. Most of the Controller logic in JSF is in the FacesServlet and the Tag implementations. Action Processors aren't controllers in the strict sense of the word. They're more of a business logic function with ties to the dispatcher.

Thank you Tim, it was the the package!
Yes I agree, i shouldn't have put my beans in a package named controller.

The reason I mentioned it is that you're not the only one I've seen doing that. I just wanted to get the word out before a lot of people get themselves all confused.

Or more confused, anyway...
