Probably you don't need all the cookies [ie cookies of all users], but you need cookies of particular request. You can get them inside HttpServlet's doGet() or doPost() methods, depending on the request type:

 public class TestServlet extends HttpServlet {

    public void doGet(HttpServletRequest request,HttpServletResponse response)
        throws ServletException, IOException {
        Cookie[] cookies = request.getCookies();
        //...
    }
 }
