Vraptor - Duvidas no FJ-28

JavaChild Membro desde: 15/03/2010 11:41:52 Mensagens: 117 Offline

Olá a todos...
Estou começando no Java, fiz alguns cursos na Caelum e comecei a fazer o projeto do FJ-28, disponibilizado no site.. tudo ia bem até eu entrar na parte do Controlador com o Vraptor... Goataria de uma ajuda... segue abaixo minhas classes controller e Dao, e o erro que estou recebendo:

Classe Controller:
package br.com.caelum.goodbuy.controller;

import java.util.List;

import br.com.caelum.goodbuy.dao.ProdutoDAO;
import br.com.caelum.goodbuy.modelo.Produto;
import br.com.caelum.vraptor.Resource;

@Resource
public class ProdutosController {

private final ProdutoDAO dao;

public ProdutosController(ProdutoDAO dao){
this.dao = dao;
}

public List<Produto> lista(){
return dao.listaTudo();
}

}

Classe DAO:

package br.com.caelum.goodbuy.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.Transaction;

import br.com.caelum.goodbuy.infra.CriadorDeSession;
import br.com.caelum.goodbuy.modelo.Produto;
import br.com.caelum.vraptor.ioc.Component;

@Component
public class ProdutoDAO {

private final Session session;

public ProdutoDAO(){
this.session = CriadorDeSession.getSession();
}

public void salva(Produto produto) {
Transaction tx = session.beginTransaction();
session.save(produto);
tx.commit();
}
public void altera(Produto produto) {
Transaction tx = session.beginTransaction();
session.update(produto);
tx.commit();
}

public Produto procura(Long id) {
Produto produto =(Produto)session.load(Produto.class, 1L);
return produto;
}
public void remove(Produto produto){
Transaction tx = session.beginTransaction();
session.delete(produto);
tx.commit();

}
@SuppressWarnings("unchecked")
public List<Produto> listaTudo(){
return this.session.createCriteria(Produto.class).list();

}

}

Erro:

Bem, espero que algu´´em consiga me ajudar...

Oi Lucas!

Ta dando uma "java.lang.NoClassDefFoundError: org/hibernate/Session". Isso indica que devem estar faltando JARs do Hibernate no seu projeto. Dá uma conferida na pasta WEB-INF/lib e vê se está tudo lá

[]'s

se nao estiver baixa esse arquivo => http://vraptor3.googlecode.com/files/vraptor-3.1.1.zip

dentro da pasta lib/opicional ... la dentro contem todos os jars do hiberante

Realmente estavam faltando alguns Jars... obrigado, hein!
