Estou com problemas na hora de fazer a listagem ou adição de usuários. A classe e o erro que o tomcat exibe são os seguintes:

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();
	
	public void intercept(LogicFlow flow) throws LogicException, ViewException {

		flow.execute();
		
		if (factory.hasTransaction()) {
			factory.rollback();
		}
		factory.close();
	}
	
	@Out(key="br.com.caelum.lojavirtual.dao.DaoFactory")
	public DaoFactory getFactory() {
		return factory;
	}
}

exception

Biom pelo oq percebi, vc esta usando a aplicação de exemplo do VRaptor, ou criou uma seguindo os modelos.

  • De uma olhada nos jars de sua aplicação;
  • Verifique o arquivo hibernate.cfg.xml no diretorio src/
java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration

Ele ta certinho, a senha, o loguin e o nome do schema tambem. E a classe HibernateUtil ta chamando ele no local certo.

  </session-factory>
</hibernate-configuration>

package br.com.caelum.lojavirtual.util;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

	private static SessionFactory factory;

	static {
		Configuration conf = new AnnotationConfiguration();
		conf.configure("/br/com/caelum/lojavirtual/util/hibernate.cfg.xml");
		factory = conf.buildSessionFactory();
	}
	
	public static Session getSession() {
		return factory.openSession();
	}

}

não sei o que pode estar errado.
