Java.lang.NullPointerException - serialFactory[RESOLVIDO]

Olá Pessoal!

Criei uma classe no meu sistema ListenerFasesJSF e nela tem o seguinte:

package br.com.modelo.controle;

import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;

public class ListenerFasesJSF implements PhaseListener {

	@Override
	public void beforePhase(PhaseEvent fase) {
		System.out.println("Antes da Fase: "+fase.getPhaseId());
	}
	
	@Override
	public void afterPhase(PhaseEvent fase) {
		System.out.println("Depois da Fase: "+fase.getPhaseId());		
	}

	@Override
	public PhaseId getPhaseId() {
		return PhaseId.ANY_PHASE;
	}

}

Quando executo o sistema ele mostra o seguinte erro no browse; java.lang.NullPointerException - serialFactory

GOSTARIA DE SABER O QUE FAZER PARA SOLUCIONAR ESTE PROBLEMA!

O problema era porque no arquivo faces-config.xml tinha o seguinte erro:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"

		<phase-listener>br.com.modelo.ses.controle.ListenerFasesJSF</phase-listener>	aqui esta o erro, é o caminho declarado que está incorreto
                                <phase-listener>br.com.modelo.controle.ListenerFasesJSF</phase-listener> este é o caminho correto!!!
