strange servlet behavior

Hi,

the following Servlet (sample from the o'reilly book)  increments the
visit-counter on reload and works well with apache mod_jserv 0.9.11, 

(apache + mod_jserv - ok)
http://chagall.diff.uni-tuebingen.de/servlet/SessionTracker

but does not increment its counter when accessed via jigsaw.

(jigsaw 2.0.1 - no incrementing)
http://chagall.diff.uni-tuebingen.de:8001/servlets/SessionTracker

Is there anything else to configure? I understood the documentation as the
servlets directory could be used to have Servelets automaticaly installed.

the code
--------------------------------------------------------------------------

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class SessionTracker extends HttpServlet {

  public void doGet(HttpServletRequest req, HttpServletResponse res)
                               throws ServletException, IOException {
    res.setContentType("text/html");
    PrintWriter out = res.getWriter();

    // Get the current session object, create one if necessary
    HttpSession session = req.getSession(true);

    Integer count = (Integer)session.getValue("tracker.count");
    if (count == null)
      count = new Integer(1);
    else
      count = new Integer(count.intValue() + 1);
    session.putValue("tracker.count", count);

    out.println("<HTML><HEAD><TITLE>SessionTracker</TITLE></HEAD>");
    out.println("<BODY><H1>Session Tracking Demo</H1>");

    out.println("You've visited this page " + count +
      ((count.intValue() == 1) ? " time." : " times."));

    out.println("<P>");

    out.println("<H2>Here is your session data:</H2>");
    String nS = new String((session.isNew() ? "NEU" : "ALT"));

    out.println("Session ist  " + nS + "<BR>");
    String[] names = session.getValueNames();
    for (int i = 0; i < names.length; i++) {
      out.println(names[i] + ": " + session.getValue(names[i]) + "<BR>");
    }
    out.println("</BODY></HTML>");
    out.close();
  }
}
