O erro 404 acontece quando você chama o método novo(), creio eu seja para mostrar o form para cadastrar o usuário, ou quando você chama o método adiciona()?

Obs: Dentro da pasta WEB_INF/jsp/usuarios você tem que ter a jsp novo.jsp e dentro de WEB_INF/jsp/produtos a jsp lista.jsp

Quando chamo o metodo novo e eu tenho sim o novo.jsp.
Estava faltando a anotacao @resource no controller

Mais agora esta dando este erro

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'criadorDeSessionFactory': Invocation of init method failed; nested exception is java.lang.OutOfMemoryError: PermGen space
Vc sabe oque é?

F
fred_cbranco

Pelo que entendi o erro na CriadordeSessionFactory.
Mais eu nao sei onde que esta tentando criar esta carniça rsss

L
Lucas_Cavalcanti

PermGen em dev geralmente é qdo vc usa o auto-deploy do servidor. Basta reiniciá-lo de verdade que funciona.

Bom outra duvida galera
Eu Criei a pasta admin e dentro dela eu coloquei o arquivo admin.jsp
no meu produtosController eu coloquei esta logica:

@Get @Path("/admin/admin")
    public List<Produto> lista1() {
        return dao.listaTudo();
}

NO meu ProdutoDao
esta assim

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

quando eu acesso a url http://localhost:8080/modular1/admin/admin
ele nao teria que trazer o arquivo lista1?
Ele esta dando erro 404.
Mais no console ele esta executando a lista do hibenate oque pode ser?
Obrigado

L
Lucas_Cavalcanti

existe o arquivo /WEB-INF/jsp/produtos/lista1.jsp ?

o @Path não influencia no caminho do jsp

F
fred_cbranco

Lucas Cavalcanti:
existe o arquivo /WEB-INF/jsp/produtos/lista1.jsp ?

o @Path não influencia no caminho do jsp

eu achei que o lista1 deveria estar na pasta admin!

F
fred_cbranco

Deu certo obrigado

F
fred_cbranco

MAis um erro bobo
A ideia aqui é quando eu acessar a url http://localhost:8080/modular1/admin
ele me abra o arquivo novo.jsp para eu cadastrar um novo admin

entao segue meu controler:

vc precisa anotar o método novo com @Get("/admin")

Valeu meu Brother muito obrigado era isso mesmo.
Estou a 48 horas ligado direto sem dormir para poder entregar este projeto eheheheeh

fred_cbranco

Este é um outro erro mais nao vou abrir outro topico para ele nao.
Sequinte o cadastro de admin funciona beleza mais quando vou fazer login ele da o sequinte erro.

bom segue ai minha dao e minha controler
Primeiro a dao

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package br.com.caelum.goodbuy.dao;

import br.com.caelum.goodbuy.infra.CriadorDeSession;
import br.com.caelum.goodbuy.modelo.Useradmin;
import br.com.caelum.vraptor.ioc.Component;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.hibernate.criterion.Restrictions;



/**
 *
 * @author Fred
 */
@Component
public class AdminDao {
    private final Session session;
    public AdminDao() {
    this.session = CriadorDeSession.getSession();
}
    public boolean existeAdmin(Useradmin useradmin) {
        Useradmin encontrado = (Useradmin) session.createCriteria(Useradmin.class).add(Restrictions.eq("login", useradmin.getLogin())).uniqueResult();
        return encontrado != null;
}
    public void adiciona(Useradmin useradmin) {
        Transaction tx = this.session.beginTransaction();
        this.session.save(useradmin);
        tx.commit();
    }
    public Useradmin carrega(Useradmin useradmin) {
        return (Useradmin) session.createCriteria(Useradmin.class).add(Restrictions.eq("login", useradmin.getLogin())).add(Restrictions.eq("senha", useradmin.getSenha())).uniqueResult();
}

    }

O erro aparentemente e neste metodo carrega

public Useradmin carrega(Useradmin useradmin) {
        return (Useradmin) session.createCriteria(Useradmin.class).add(Restrictions.eq("login", useradmin.getLogin())).add(Restrictions.eq("senha", useradmin.getSenha())).uniqueResult();

Agora meu controller

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package br.com.caelum.goodbuy.controller;

import br.com.caelum.goodbuy.dao.AdminDao;
import br.com.caelum.goodbuy.modelo.AdminWeb;

import br.com.caelum.vraptor.Get;
import br.com.caelum.vraptor.Path;
import br.com.caelum.vraptor.Post;
import br.com.caelum.vraptor.Resource;
import br.com.caelum.vraptor.Result;
import br.com.caelum.vraptor.Validator;
import br.com.caelum.vraptor.validator.ValidationMessage;



/**
 *
 * @author Fred
 */

@Resource
public class AdminController {
    private final AdminDao dao;
    private final Result result;
    private final Validator validator;
    private final AdminWeb adminWeb;
    public AdminController(AdminDao dao, Result result, Validator validator, AdminWeb AdminWeb) {
        this.dao = dao;
        this.result = result;
        this.validator = validator;
        this.adminWeb = AdminWeb;
}
    @Post @Path("/admin/novoadmin")
    public void adiciona(Useradmin useradmin) {
        if (dao.existeAdmin(useradmin)) {

    validator.add(new ValidationMessage("Login já existe", "usuario.login"));
        }
            validator.onErrorUsePageOf(AdminController.class).novo();
            dao.adiciona(useradmin);
            result.redirectTo(ProdutosController.class).lista1();
}
    @Get("/admin/novoadmin")
    public void novo() {

}
    @Get @Path("/admin/login")
        public void login() {
}
    @Post @Path("/admin/login")
    public void login(Useradmin useradmin) {
        Useradmin carregado = dao.carrega(useradmin);
        if (carregado == null) {
        validator.add(new ValidationMessage("Login e/ou senha inválidos", "useradmin.login"));
        }
        validator.onErrorUsePageOf(AdminController.class).login();
        adminWeb.login(carregado);
        result.redirectTo(ProdutosController.class).formulario();
}
    @Path("/logout")
        public void logout() {
        adminWeb.logout();
        result.redirectTo(ProdutosController.class).lista();
}

}

No controle o erro é no:

[/code]

public void login(Useradmin useradmin) {

Useradmin carregado = dao.carrega(useradmin);

if (carregado == null) {

validator.add(new ValidationMessage(“Login e/ou senha inválidos”, “useradmin.login”));

}

validator.onErrorUsePageOf(AdminController.class).login();

adminWeb.login(carregado);

result.redirectTo(ProdutosController.class).formulario();

[/code]

Eu ja fundi meus neuronios estou desde quarta a noite mechendo nisso alguem pode me ajudar?
Lucas?

P
pedruhenrik 
return (Useradmin) session.createCriteria(Useradmin.class).add(Restrictions.eq("login", useradmin.getLogin())).add(Restrictions.eq("senha", useradmin.getSenha())).uniqueResult();

se vc fizer a query na mão direto no banco o q retorna?

se não me engano .uniqueResult(); retorna nulo se não encontrar.

att,

L
Lucas_Cavalcanti

nessa linha:

Caused by: java.lang.NullPointerException  
        at br.com.caelum.goodbuy.dao.AdminDao.carrega(AdminDao.java:37)

vê o que pode estar nulo.

por exemplo, o useradmin, ou a session
