Problema JSF

Olá Galera, estou começando a trabalhar com JSF e tive um probleminha e gostaria que vocês me dessem uma ajuda.

Segue meu código:

Entidade:

package br.com.integrator;

import java.io.Serializable;

public class MeuBean {
	private String nome;

	public String getNome() {
		return nome;
	}

	public void setNome(String nome) {
		this.nome = nome;
	}	
}

Controller:

package br.com.integrator.controller;

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

import br.com.integrator.MeuBean;

public class Controle  {
	private MeuBean meuBean;
	
	public Controle() {
		meuBean = new MeuBean();
	}

	public MeuBean getMeuBean() {
		return meuBean;
	}

	public void setMeuBean(MeuBean meuBean) {
		this.meuBean = meuBean;
	}
	
	public String acao() {
		boolean sucesso = true;
		FacesContext context = FacesContext.getCurrentInstance();
		if (meuBean.getNome()!= null) {
			for ( int i = 0;i<meuBean.getNome().length();i++) {
				char c = meuBean.getNome().charAt(i);
				if(!Character.isLetter(c)&&!Character.isSpace(c)) {
					String msg = "Digite Somente caracteres alfabéticos";
					FacesMessage message = new FacesMessage(msg);
					context.addMessage("formulario", message);
					sucesso = false;
					break;
				}
			}
		} else {
			sucesso = false;
		}
		return (sucesso ? "sucesso" : "falha");
	}
}

O problema acontece, após clicar no botão enviar da página trabComJSF.jsp.
O erro é o seguinte:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: viewId:/trabComJSF.jsf - View /trabComJSF.jsf could not be restored.

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.26 logs.

Alguém tem alguma idéia do que seja o problema?

Agradeço desde já.
