Question : how to add cookie using a servlet

I am trying to add a cookie using a servlet. However, when I go Mozilla and check for the cookie being added, it is not there. The browser does not contain the cookie.

Please, see code below. Can someone tell me what I a missing so that the cookie is added to the browser. I am running the application local. Therefore, the new cookie should be under localhost. I noticed that cookie JSESSIONID gets added by default but mine does not reflect.

          protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException
    {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {

            Cookie cookie = null;
            Cookie[] cookies = request.getCookies(); //get the 20 cookies that can be set by a website.


            UUID cookieID = UUID.randomUUID();

            cookie = new Cookie("cookieTest", cookieID.toString());
            cookie.setMaxAge(315360001);

            response.addCookie(cookie);

        }
        catch(Exception ex)
        {
            String ss = ex.getMessage();
        }
        finally
        {
            //out.close();
        }
    }

        
      

Answer : how to add cookie using a servlet

OK - so the code itself works.

Ah - include.

That explains it I am afraid - jsp:include is equivalent to a RequestDispatcher.include which javadoc explicitly says: "The ServletResponse object has its path elements and parameters remain unchanged from the caller's. The included servlet cannot change the response status code or set headers; any attempt to make a change is ignored." (from http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/RequestDispatcher.html - and it had not changed in newer versions)

The cookie is a header... so you just cannot do it from there.
So you need either to move the cookie somewhere else or to find another way to get the servlet code in the JSP.
