conseguir Alisson, agora estou com o problema para minha classe Bean se comunicar com meu xHTML stou usando Spring como injeção de dependencia:

package br.com.fitecproject.controllers;

import javax.inject.Inject;

import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;

import br.com.fitecproject.daos.UsuarioDao;
import br.com.fitecproject.models.Usuario;



@Controller
public class LoginController
{
    private Usuario usuario = new Usuario();

    private String mensagem;

    @Inject
    UsuarioDao dao;


    @Transactional
    public void gravarUsuario(){
        this.dao.incluir(usuario);
    }

    public void enviarMensg(){
        this.mensagem = "Olá Mundo";
    }

    public String getMensagem() {
        return mensagem;
    }


}
