Getting cookie in servlet

Question

I\'m trying to get cookie in servlet using

Cookie[] cookie = request.getCookies();

but cookie is always null.

Answer 1

According to docs getCookies() Returns an array containing all of the Cookie objects the client sent with this request. This method returns null if no cookies were sent.

Did you add the cookie correctly? If yes, you should be able to iterate through the list of cookies returned with

Cookie[] cookies = request.getCookies();

for (int i = 0; i < cookies.length; i++) {
  String name = cookies[i].getName();
  String value = cookies[i].getValue();
}

If no...

Cookies are added with the addCookie(Cookie) method in the response object!
