Olá Pessoal.

Estou com um problema durante a realização dos exercícios da Apostila da Caelum fj28.

---- Código Interceptor ----
package com.br.loja.interceptor;

import org.vraptor.Interceptor;

import org.vraptor.LogicException;

import org.vraptor.LogicFlow;

import org.vraptor.annotations.Out;

import org.vraptor.view.ViewException;

import com.br.loja.dao.DaoFactory;

public class DaoInterceptor implements Interceptor {

private final DaoFactory factory = new DaoFactory();

public void intercept(LogicFlow flow) throws LogicException, ViewException {
	//Executa a lógica
	flow.execute();
	
	//Se sobrou transação sem comitar, faz rollback
	if(factory.hasTransaction()){
		factory.rollback();
	}
	factory.close();
}

@Out(key="com.br.loja.dao.DaoFactory")
public DaoFactory getFactory() {
      return factory;
}

}

Segue abaixo msg de erro.

Agradeço a ajuda.

java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

provavelmente esta classe não foi encontrada no seu projeto. Baixe os jars do “slf4j”, adicione ao classpath e tente rodar de novo pra ver oq acontece.
