O erro é no meu produtoDao acredito que no metodo que lista mais eu sou muito cru no java e nao to conseguindo encontrar

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(Session session) {
		this.session = session;
		}

	public void salva(Produto produto) {
		
		Transaction tx = session.beginTransaction();
		session.save(produto);
		tx.commit();
	}
	public void atualiza(Produto produto) {
		Transaction tx = session.beginTransaction();
		session.update(produto);
		tx.commit();
	}
	public void remove(Produto produto) {
		Transaction tx = session.beginTransaction();
		session.delete(produto);
		tx.commit();
	}
	public List<Produto> listaTudo() {
		return this.session.createCriteria(Produto.class).list();
		}
	public Produto carrega(Long id) {
		return (Produto) this.session.load(Produto.class, id);
		}


}

Este é meu trabalho de modulo da facudade estou desesperado

pedruhenrik 19 de jun. de 2011

utilize as tags CODE para colocar seu código.

o seu ProdutoDao precisa ser iniciado/instanciado...

por exemplo no meu controller eu faço assim:

@Resource
public class AdminController {
	private final Result result;
	private ClienteDAO daoCliente;
	private UsuarioDAO daoUsuario;
	private RequisicaoDAO daoRequisicao;

	public AdminController(Result result, ClienteDAO daoCliente,
			UsuarioDAO daoUsuario, RequisicaoDAO daoRequisicao) {
		this.result = result;
		this.daoCliente = daoCliente;
		this.daoUsuario = daoUsuario;
		this.daoRequisicao = daoRequisicao;
	}
}

no meu web.xml:

&lt;context-param&gt;
  &lt;param-name&gt;br.com.caelum.vraptor.packages&lt;/param-name&gt; 
  &lt;param-value&gt;br.com.caelum.vraptor.util.hibernate&lt;/param-value&gt; 
  &lt;/context-param&gt;

pq o vraptor q gerenciar td.

fred_cbranco 19 de jun. de 2011

Mais o meu esta instanciado

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;
import br.com.caelum.vraptor.Result;
@Resource
public class ProdutosController {
	
		private final ProdutoDao dao;
		private final Result result;
			public ProdutosController(ProdutoDao dao, Result result) {
				this.dao = dao;
				this.result = result;
			}
		public List<Produto> lista() {
		return dao.listaTudo();
		}
		public void adiciona(Produto produto) {
			dao.salva(produto);
			result.redirectTo(this).lista();
			}
		public void formulario() {
		}
		public Produto edita(Long id) {
			return dao.carrega(id);
		}
		public void altera(Produto produto) {
			dao.atualiza(produto);
			result.redirectTo(this).lista();
		}
		public void remove(Long id) {
			Produto produto = dao.carrega(id);
			dao.remove(produto);
			result.redirectTo(this).lista();
		}

}

pedruhenrik 19 de jun. de 2011

aonde vc abre a sessão?

att,

fred_cbranco 19 de jun. de 2011

Abro na classe CriadordeSession

package br.com.caelum.goodbuy.infra;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.ioc.ComponentFactory;

@Component
public class CriadorDeSession implements ComponentFactory<Session> {

	private final SessionFactory factory;
	private Session session;
	public CriadorDeSession(SessionFactory factory) {
	this.factory = factory;
	}
	@PostConstruct
	public void abre() {
	this.session = factory.openSession();
	}
	public Session getInstance() {
	return this.session;
	}
	@PreDestroy
	public void fecha() {
	this.session.close();
	}

}

pedruhenrik 19 de jun. de 2011

http://www.guj.com.br/java/245227-erro-formulario-vraptor#1269642

com base nesse seu outro post:

java.lang.NullPointerException br.com.caelum.goodbuy.infra.CriadorDeSession.getInstance(CriadorDeSession.java:16) br.com.caelum.goodbuy.infra.CriadorDeSession.getInstance(CriadorDeSession.java:1)

ta dando pau na hora de criar a sessão.

utlizando essa sua classe CriadorDeSession tem q configurar algo no web.xml ? nunca usei dessa maneira.

será q esses links pode ajudar?

att,

Lucas_Cavalcanti 19 de jun. de 2011

fred, o que você está retornando no CriadorDeSessionFactory? posta a classe aqui, plz. Como tá dando NullPointer, a única explicação é a factory estar nula

fred_cbranco 20 de jun. de 2011

Fala lucas eu estou seguindo a apostila da caelum.
alem desta classe eu tenho a CriadorDeSessionFactory

segue o codigo dela

package br.com.caelum.goodbuy.infra;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;

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

import br.com.caelum.vraptor.ioc.ApplicationScoped;
import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.ioc.ComponentFactory;

@Component
@ApplicationScoped
public class CriadorDeSessionFactory implements ComponentFactory<SessionFactory> {

	private SessionFactory factory;
	@PostConstruct
	public void abre() {
	AnnotationConfiguration configuration = new AnnotationConfiguration();
	configuration.configure();
	this.factory = configuration.buildSessionFactory();;
	}
	public SessionFactory getInstance() {
	return this.factory;
	}
	@PreDestroy
	public void fecha() {
	this.factory.close();
	}
	
	}

Este projeto faz parte do meu tcc, onde na faculdade ninguem acredita que eu consiga fazer em java. todos foram para o PHP mais eu quero em java.

Lucas_Cavalcanti 20 de jun. de 2011

e ainda tá dando Nullpointer no getInstance do CriadorDeSession?

bom, você pode pular essa parte da apostila, remover as classes CriadorDeSession e CriadorDeSessionFactory e colocar essa configuração no seu web.xml:

<context-param>
    <param-name>br.com.caelum.vraptor.packages</param-name>
    <param-value>br.com.caelum.vraptor.util.hibernate</param-value>
</context-param>

isso também já inclui o interceptor de transações, então é só usar direto a session nos seus daos.

fred_cbranco 20 de jun. de 2011

vc sabe como posso fazer isso? so alterar o xml e excluir as classes?
sou bem cru em vraptor

fred_cbranco 20 de jun. de 2011

alguem ai ja fez este projeto? tem ele para disponibilizar?
Obrigado

Lucas_Cavalcanti 20 de jun. de 2011

sim, só alterar o xml e excluir as classes

fred_cbranco 20 de jun. de 2011

Lucas muito obrigado aquele erro ja foi agora esta com outro no arquivo jsp na linha 1

vc sabe oque pode ser?

A vc tem interesse em pegar trabalhos freelance?

FelipeThi 20 de jun. de 2011

Lucas Cavalcanti:
e ainda tá dando Nullpointer no getInstance do CriadorDeSession?

bom, você pode pular essa parte da apostila, remover as classes CriadorDeSession e CriadorDeSessionFactory e colocar essa configuração no seu web.xml:
<context-param>
    <param-name>br.com.caelum.vraptor.packages</param-name>
    <param-value>br.com.caelum.vraptor.util.hibernate</param-value>
</context-param>
isso também já inclui o interceptor de transações, então é só usar direto a session nos seus daos.

Lucas, só pra compreender. Então quer dizer que quando eu faço essa configuraçao no web.xml eu posso fazer isso no meu Dao:

private Session sessao;
public ProdutoDao(Session session){
  this.sessao = session;
}
