Code:
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class STimerOut extends HttpServlet {
// Handles the HTTP <code>GET</code> method.

// use rq to read incoming HTTP headers
// use rs to specify the HTTP response status
public void doGet(HttpServletRequest rq, HttpServletResponse rs)
throws ServletException, IOException {

// tell the browser that we are sending back html
rs.setContentType(“text/html”);

// used to modify println() statements to build a legal web page
PrintWriter out = rs.getWriter();

int t = 60;

/*
system extracts a user ID from a cookie or attached URL data, then uses
that as a key into a table of previously created HttpSession objects.
*/
HttpSession s = rq.getSession();

/*
following statements build a legal webpage
*/
out.println(“<HTML>”);
out.println(“<HEAD>”);
out.println(“<TITLE >”);
out.println(“Session TimeOut “);
out.println(“</TITLE>”);
out.println(“</HEAD>”);

out.println(“<BODY>”);
out.println(“<H1>”);
out.println(“Session TimeOut “);
out.println(“</H1>”);

out.println(“gaining the old time out ” +
s.getMaxInactiveInterval());/* getMaxInactiveInterval() gets the maximum
time in seconds for which the session remained
inactive.

out.println(“<BR>”);
out.println(“<BR>”);

s.setMaxInactiveInterval(2*t*t); /* sets the maximum time in seconds for which the
session can remain inactive.
out.println(“giving new time to get out ” +
s.getMaxInactiveInterval());

out.println(“</BODY>”);
out.println(“</HTML>”);
