Alguem sabe que problema é este?
o interessante é que no console ele lista o codigo do hibernate que seria:
Hibernate:
select
this_.id as id4_0_,
this_.descricao as descricao4_0_,
this_.nome as nome4_0_,
this_.preco as preco4_0_
from
Produto this_
eu nao estou entendendo
org.apache.jsp.WEB_002dINF.jsp.produtos.lista_jsp._jspInit(lista_jsp.java:22)
lista_jsp.java:22 alguma coisa esta nulo não?
NÃO DUPLIQUE TÓPICOS:
http://www.guj.com.br/java/245221-pra-quem-manja-de-vraptor#1269616
att,
Ola amigo é porque so depois que vi que tinha uma area so para Vraptor perdão!
Quanto a sua resposta eu nao entendi oque quis dizer!

Este é meu trabalho de modulo da facudade estou desesperado
utilize as tags CODE para colocar seu código.
o seu ProdutoDao precisa ser iniciado/instanciado…
por exemplo no meu controller eu faço assim:
[code]@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;
}
}
[/code]
no meu 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>
pq o vraptor q gerenciar td.
http://vraptor.caelum.com.br/documentacao/componentes-utilitarios-opcionais/
att,
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();
}
}
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();
}
}
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?
http://www.guj.com.br/java/217807-injecao-de-dependencia#1113017
http://www.guj.com.br/java/199378-error-criando-usuarioresolvido
att,
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
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.
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.
vc sabe como posso fazer isso? so alterar o xml e excluir as classes?
sou bem cru em vraptor
alguem ai ja fez este projeto? tem ele para disponibilizar?
Obrigado
sim, só alterar o xml e excluir as classes
Lucas muito obrigado aquele erro ja foi agora esta com outro no arquivo jsp na linha 1
