Hello
I'm trying to store all users who are logged me my system to have a
control in gwt
the beginning I did get the user who is logging in through the class I
served in
package br.projeto.server;
import br.projeto.client.User;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import br.projeto.client.GWTService;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.apache.catalina.Session;
/**
*
* @author MICHEL
*/
public class GWTServiceImpl extends RemoteServiceServlet implements
GWTService {
private User usuario;
public User getUser(String vlogin, String vsenha) {
//System.out.print("Usuario 3333333-- ");
UsuarioDao objUserDao = new UsuarioDao();
usuario = objUserDao.procura(vlogin, vsenha);
HttpServletRequest httpSession = this.getThreadLocalRequest();
HttpSession session = httpSession.getSession();
session.setAttribute("usuario",usuario);
User usua = (User) session.getAttribute("usuario");
// UsuariosAtivos.usuariosAtivos.add(usua);
// System.out.print("Usuario "+usua.getUser());
//Logado(usuario);
return usuario;
}
public void Logado(User user) {
// System.out.print("Usuario ");
if(user != null){
HttpSession httpSession =
getThreadLocalRequest().getSession();
httpSession.setAttribute("usuario",user);
User usua = (User) httpSession.getAttribute("usuario");
// System.out.print("Usuario ");
}
}
public List<User> getUsuario() {
return UsuariosAtivos.getUsuariosAtivos();
}
}
But when I try to get the users online for a class that triggered it
and not using the web.xml users are getting this from mine null class
and the following
package br.projeto.server;
/**
*
* @author MICHEL
*/
import br.projeto.client.User;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.*;
public class UsuariosAtivos extends HttpServlet implements
HttpSessionListener {
public UsuariosAtivos() {
}
public static int quantidadeSessoesAtivas;
public static List<User> usuariosAtivos = new ArrayList<User>();
public static List<User> getUsuariosAtivos()
{
return usuariosAtivos;
}
public void sessionCreated(HttpSessionEvent se) {
HttpSession httpSession = se.getSession();
User u = (User) httpSession.getAttribute("usuario");
System.out.println("session created 3.1"+u.getUser());
if(u != null)
{
System.out.println("session created 3.1");
}
else{System.out.println("esta vazio");}
String nome = u.getUser();
usuariosAtivos.add(u);
quantidadeSessoesAtivas++;
System.out.println("session created 3 Michel");
}
public void sessionDestroyed(HttpSessionEvent se) {
HttpSession httpSession = se.getSession();
User usua = (User) httpSession.getAttribute("usuario");
usuariosAtivos.remove(usua);
quantidadeSessoesAtivas--;
}
}
And within the web.xml as follows
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee";
