Adilson,

A classe onde ocorre o erro (aparentemente) é a seguinte:

br.com.caelum.lojavirtual.logic.DaoInterceptor.intercept(DaoInterceptor.java:20)

Abs,

Ok o brigao pela dica segue a classe:

package br.com.caelum.lojavirtual.logic;

import org.vraptor.Interceptor;
import org.vraptor.LogicException;
import org.vraptor.LogicFlow;
import org.vraptor.annotations.Out;
import org.vraptor.view.ViewException;

import br.com.caelum.lojavirtual.dao.DaoFactory;

public class DaoInterceptor implements Interceptor {

	private final DaoFactory factory = new DaoFactory();
	

	@Override
	public void intercept(LogicFlow flow) throws LogicException, ViewException {
		// TODO Auto-generated method stub
		
		flow.execute();
		
		//se sobrou trasanção sem comitar, faz rollback
		if(factory.hasTransaction()){
                   factory.rollback();			
		}
		
		factory.close();
	}
	
	@Out(key="br.com.caelum.lojavirtual.dao.DaoFactory")
	public DaoFactory getFactory(){
		return factory;
	}

Obrigado pela ajuda!!!
