Bean is not reached by View

Question

I am with a Requestscoped Managedbean that is not being found by my view.

Managedbean

package br.com.hidros.control.beans;

import java.io.Serializable;
import java.text.SimpleDateFormat;
import java.util.Date;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

import org.apache.commons.mail.EmailException;

import br.com.hidros.control.Email;

@ManagedBean(name="utilBean")
@RequestScoped
public class UtilBean implements Serializable {

    private static final long serialVersionUID = 1L;
    private Email email = new Email();

    /***************************************/
    /*********** Métodos Próprios **********/
    /***************************************/

    public String formatarData(Date data) {
        return new SimpleDateFormat("dd/MM/yyyy").format(data);
    }

    public void enviarEmail() {
        try {
            email.sendEmail();
        } catch (EmailException e) {
            e.printStackTrace();
        }
    }

    public void msg() {
        System.out.println("chegou");
    }
}

Answer 1

I resolved.

I had forgotten to import some jars from the method I call on the Bean. I just referenced to the desktop, where they were.

Now it worked.
