Filtros com Facelets

JavaBaby Membro desde: 11/06/2008 12:38:26 Mensagens: 90 Offline

Boa tarde colegas,

Estou com um problema, após realizar o login na minha página o filtro criado não é executado, ele executa antes do managenBean. O que estou fazendo de errado?

Segue o código:

Managen Bean

package br.com.rtkomp.managerbean;

import br.com.rtkomp.dao.UsuarioDao;
import br.com.rtkomp.entity.Usuario;
import javax.faces.context.FacesContext;

/**
 *
 * @author thiagortk
 */

public class LoginFace {

private UsuarioDao ud = new UsuarioDao();

public String user;

public String pass;

boolean logged;

public LoginFace() {

logged = false;

}

public String doLogin(){

try{
        
            Usuario u = ud.validatedUser(user, pass);

logged = (u == null) ? false : true;

FacesContext.getCurrentInstance().getExternalContext().getSessionMap().
                    put("idLogged", logged);

if(logged == false)
                return "invalidLogin";

}
        catch(Exception ex){
            // TODO implementar tratamento de Erro
        }

return "gotoIndex";

}

public String getPass() {
        return pass;
    }

public void setPass(String pass) {
        this.pass = pass;
    }

public String getUser() {
        return user;
    }

public void setUser(String user) {
        this.user = user;
    }

}

Já agradecendo.

Abraços.

Bom calma ai veio,vamos ver se eu entendi:

O seu filtro não está executando?

ou o seu filtro esta executando antes do seu MB?

Caso for a segunda opção, esta certo,pq o filtro executa antes do front controller!então por isso
que ele passa primeiro no filtro, e depois vai para o front controller que ira chamar a sua MB!!
se voce quer redirecionar faça no proprio MB e manda um hardcode paprao para a navegacao
se o usuario nao estiver logado.

Abraços

Puts, então tem algo mais estranho ainda mano, veja que estou fazendo o redirecionamento no managen bean com "gotoIndex", mas não vai, ele fica na tela de login, e eu depurei o managen bean pra confirmar se o "gotoIndex" é executado e está ok. É a primeira vez que faço algo com facelets, tem alguma coisa que tenho que fazer de difirente no navigation case?

Muito obrigado.

Acho q achei o erro acho, vc ta chamando uma pagina jsf , tem q chamar .xhtml

exemplo:

este é um exemplo meu, é so vc trocar a suas .jsf para .xhtml!

abraço

Sua navegacao:

a onde esta negrito, vc troca por .xhtml

vlws irmao, abraço
