Im a bit confused cuz I were told session tracking automatically
switched from cookies to url rewriting when cookies arent enabled in
browser but it doesn't seem to work with this simple example :
package coreservlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.net.*;
import java.util.*;
/** Simple example of session tracking.
* Taken from Core Servlets and JavaServer Pages
* from Prentice Hall and Sun Microsystems Press,

public class ShowSession extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String title = "Session Tracking Example";
HttpSession session = request.getSession(true);
String heading;
// Use getAttribute instead of getValue in version 2.2.
Integer accessCount =
(Integer)session.getAttribute("accessCount");
if (accessCount == null) {
accessCount = new Integer(0);
heading = "Welcome, Newcomer";
} else {
heading = "Welcome Back";
accessCount = new Integer(accessCount.intValue() + 1);
}
// Use setAttribute instead of putValue in version 2.2.
session.setAttribute("accessCount", accessCount);
out.println(ServletUtilities.headWithTitle(title) +
"<BODY BGCOLOR=\"#FDF5E6\">\n" +
"<H1 ALIGN=\"CENTER\">" + heading + "</H1>\n" +
"<H2>Information on Your Session:</H2>\n" +
"<TABLE BORDER=1 ALIGN=\"CENTER\">\n" +
"<TR BGCOLOR=\"#FFAD00\">\n" +
" <TH>Info Type<TH>Value\n" +
"<TR>\n" +
" <TD>ID\n" +
" <TD>" + session.getId() + "\n" +
"<TR>\n" +
" <TD>Creation Time\n" +
" <TD>" +
new Date(session.getCreationTime()) + "\n" +
"<TR>\n" +
" <TD>Time of Last Access\n" +
" <TD>" +
new Date(session.getLastAccessedTime()) + "\n" +
"<TR>\n" +
" <TD>Number of Previous Accesses\n" +
" <TD>" + accessCount + "\n" +
"</TABLE>\n" +
"</BODY></HTML>");
}
/** Handle GET and POST requests identically. */
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
Could anyone help me ? Is there a thing to configure to accept session
tracking ?
