Olá Bravox e colegas do GUJ!
Bom Dia!
Se puderem me ajudar outra vez, agradeço.
Fiz da seguinte maneira:
Na minha classe que verifica o usuário, via SQL no banco, coloquei como me orientou:
...
while (rs.next()){
url_="loginOK";
HttpSession session =(HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(false);
session.setAttribute("usuCod", "OK" );
... }
A minha classe FilterLogin está assim:
package util;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpSession;
public class FilterLogin implements Filter {
public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpSession session = request.getSession();
// recupera o usuario adm logado da sessão
Object login = session.getAttribute("usuCod");
RequestDispatcher dispatcher = null;
// tem usuario administrator ?
if( login == null ){
//então envia para a pagina de acesso invalido
dispatcher = req.getRequestDispatcher("/erroLogin.jsp");
}
else {
// libera o acesso a pagina
dispatcher = req.getRequestDispatcher(request.getRequestURI());
}
dispatcher.forward(req, resp);
}
public void init(FilterConfig arg0) throws ServletException {
}
public void destroy() {
}
}
o meu web xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<filter-mapping>
<filter-name>FilterLogin</filter-name>
<url-pattern>/Pharma/faces/*</url-pattern> <!-- e filtrado todas as requisiçoes com essa url -->
</filter-mapping>
</web-app>
Acontece que ao executar, não está entrando no filter. Pude notar que no web.xml tem a tag <url-pattern> dependendo do que eu coloco alí a página nem é exibida, dá o erro do tamcat:
type Status report
message /Pharma/Pharma/
description The requested resource (/Pharma/Pharma/) is not available.
Pode me ajudar?
Obrigado!
Tenham uma excelente semana!
