I have the follow problem.
I put a string in servlet session and then i try to read the value from a jsp page.
When i get the objet session within jsp page I obtain a null value. here is the
servlet and jsp source code.
// -*- mode: java -*-
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
public final class insIntoSession extends HttpServlet implements CostantiServlet
{
private HttpSession session = null;
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
String saluti = new String("Ciao Salvatore");
session = req.getSession(false);
try
{
if (session == null)
log("Non sono riuscito a creare la sessione ");
else
log("Inserisco nella sessione il valore "+saluti);
session.putValue("insIntoSession.saluti",saluti);
res.sendRedirect("/sgti/jsp/vediSessione.jsp");
}
catch(Exception e)
{
throw new UnavailableException(this,DB_ERROR_CONNECTION);
}
}
/**
* Before dying out...
*/
public void destroy() {
log("Servlet insIntoSession distrutta.");
}
}
