JSESSIONID cookie missing after creating session

We are creating session in our application after successful login of the user using the following code

HttpSession session = request.getSession(true);
sesssion.setAttribute("adminUserName", principalName);

Now it should create a cookie in the browser with JSESSIONID as soon as we send the response and redirect to some other page which is a JSP. Now we are trying to print all the cookies from the request in the JSP by using the following code.

Cookie cookie = null;
      Cookie[] cookies = null;

      cookies = request.getCookies();
      if (cookies != null) {
         out.println("<h2> List of cookies : </h2>");
         for (int i = 0; i < cookies.length; i++) {
            cookie = cookies[i];
            out.print("Name : " + cookie.getName() + ",  ");
            out.print("Value: " + cookie.getValue() + " <br/>");
         }
      } else {
         out.println("<h2>No cookies founds</h2>");
      }

but the result is No cookies founds and the problem it is creating is that, in the next servlet, we are getting the session from request object as null.

What could be the possible cause?

I do not see anywhere where you add the cookie on your code.For example :

Cookie firstCookie= new Cookie("adminUserName",
request.getParameter("principalName"));
response.addCookie( firstCookie);

Second you get your session 

request.getSession(false);

This should not create a new session just return the current one if exists.Otherwise return null.
