Boa noite gente, estou tentando aprender a utilizar o Vraptor, sou iniciante em java e no framework.
Bom, estou seguindo a apostila do curso fj-28 da caelum, e ao tentar rodar o exemplo de listagem de produtos, não funciona,
seguem os códigos das minhas classes:
ProdutoDao:
package br.com.vraptor.dao;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
import br.com.caelum.vraptor.ioc.Component;
import br.com.vraptor.domain.Produto;
import br.com.vraptor.infra.CriaSession;
@Component
public class ProdutoDao {
private final Session session;
public ProdutoDao() {
super();
this.session = CriaSession.getSession();
}
public void salva(Produto produto) {
Transaction tx = session.beginTransaction();
session.save(produto);
tx.commit();
}
public List<Produto> listaTudo(){
return this.session.createCriteria(Produto.class).list();
}
} e o meu ProdutosController:
package br.com.vraptor.controller;
import java.util.List;
import br.com.caelum.vraptor.Resource;
import br.com.vraptor.dao.ProdutoDao;
import br.com.vraptor.domain.Produto;
@Resource
public class ProdutosController {
private final ProdutoDao dao;
public ProdutosController(ProdutoDao dao){
this.dao = dao;
}
public List<Produto> lista(){
return dao.listaTudo();
}
}ao acessar o url /produtos/lista, eu recebo a seguinte mensagem de erro:
HTTP Status 500 -

Bom gente, me desculpem a mensagem longa, mas acho que sem essas informações seria difícil me ajudarem, obrigado.
