Okay, another question....
I am programming cookies for the first time. I have three links that
my servlet goes to (nytimes.com, washingtontimes.com, tribune.com) and
I'm supposed to have three cookies that keep track of this.....

First I setup the three cookies, then I do a simple req.getParameter
from the radio buttons to check to see what is being passed, and I add
the cookie then.

Below is my code - what am I doing wrong?

Cookie n = new Cookie("nyc", "0");
        n.setMaxAge(60*60*24*7);
        Cookie w = new Cookie("wash","0");
        w.setMaxAge(60*60*24*7);
        Cookie t = new Cookie("trib","0");
        t.setMaxAge(60*60*24*7);
        if(req.getParameter("Pages").equals("Wash"))
        {
            resp.addCookie(w);
            //resp.sendRedirect("http://www.washingtonpost.com");
        }
        if(req.getParameter("Pages").equals("Nytimes"))
        {
            resp.addCookie(n);
            //resp.sendRedirect("http://www.nytimes.com");
        }
        if(req.getParameter("Pages").equals("Trib"))
        {
            resp.addCookie(t);
            //resp.sendRedirect("http://www.chicagotribune.com");
        }
        Cookie[] cookies = req.getCookies();
        if(cookies != null)
        {
            for(int i=0;i<cookies.length;i++)
            {
                Cookie name = cookies[i];
                if(name.getName().equals("wash"))
                {
                    int countw=Integer.parseInt(w.getValue());
                    countw++;
                    w.setValue(Integer.toString(countw));
                }
                if(name.getName().equals("nyc"))
                {
                    int countn=Integer.parseInt(n.getValue());
                    countn++;
                    n.setValue(Integer.toString(countn));
                }
                if(name.getName().equals("trib"))
                {
                    int countt=Integer.parseInt(t.getValue());
                    countt++;
                    t.setValue(Integer.toString(countt));
                }
            }
        }
        resp.setContentType("text/html");
        PrintWriter out = resp.getWriter();
        out.println("<html>" +
        "<head><title>" +
        "DirectIt2Servlet.html" + "</title></head>" +
        "<body>" +
        "<form action=\"/MyWebApp/DirectIt2Servlet\">" +
        "<p>" + "Below are three choices for three different web pages that
you can go to. Click on the radio button, and then click on submit to
go to that page." + "<br />" +
        "<br />" + "http://www.washingtonpost.com" +
        "<input type=\"radio\" name=\"Pages\" value=\"Wash\" />" +

The first thing you are doing wrong is debugging
a servlet/JSP rather than making a pure HTML/JS
solution, validating the HTML (and the JS if
applicable) and debugging that.

Once that works correctly, it will be much easier
to make it work correctly in J2EE code.

It might help also, when asking questions about
the HTML/JS version (on an appropriate group) to
state the behaviour you expect, and the actual
behaviour observed.

to answer that question, you want to see what sort of cookie your
browser keeps when you do this manually.
