I create a cookie, set a comment and an age, res.add(cookie)...
But when I read it at the next page, all attributes seem to be missing. Only name and value show up. The rest are null and -1 for max age... How come?

Um, come to think of it, how can I tell if it's a session or a stored cookie? I can't find it anyway in the cookies directory (windows 2000), even if I don't close the browser.

Check your browser for cookie setting.  If the browser is not allowing the cookie, then you won't find anything.

I have set "medium" level on IE, and I'm using lots of cookie sites (like EE) without problems.

Cookie c = new Cookie(name, value);
response.addCookie(c);

This way only you are adding rite.

Are you getting your cookies in the request.  Atleast few of your cookies that you set.

Can you post your servlet also

Servlet1

Cookie cookie = new Cookie("databank", "username");
cookie.setComment("This is a test cookie");
cookie.setMaxAge(4000);
res.addCookie(cookie);

Servlet 2

Cookie[] cookies = req.getCookies();
if (cookies!=null) {
  for (int i=0; i<cookies.length; i++) {
  System.out.println(cookies[i].getName());
  System.out.println(cookies[i].getValue());
  System.out.println(cookies[i].getComment());
  System.out.println(cookies[i].getPath());
  System.out.println(cookies[i].getVersion());
  System.out.println(cookies[i].getDomain());
  System.out.println(cookies[i].getMaxAge());
  System.out.println(cookies[i].getSecure());
}

As simple as it can get :)

            } else {
                  System.out.println("No cookies set");
            }

Comment this

// cookie.setMaxAge(4000);

then use

Try this.

cookie.setDomain("<exactly your domain or IP>");

Browser exactly attaches the cookies to the corresponding website.

No good. Result remains the same. I even set IE to the lowest privacy/security level.
It's so simple... what on earth am I missing?!

Could it be the server itself? I'm using Tomcat 5 for the time being...

I donno about tomcat.  I have used cookies in websphere.  I have done that coding in this way only.

May be you can try some other server.

Thanks for the link.

To be honest, I never had to run the J2EE server before. What happens is that the server starts ok, I can access the default page at port 8000, but the j2ee-admin page does not work at all; 404 error.

EE1.3, SE1.4
