Retrieving Cookies from the HTTP Request

Use the getCookies() method of the HttpServletRequest to retrieve an array of all cookies in the request.

Loop down the array entries calling getName() on each Cookie object until you find the cookie you want to retrieve.

Call the getValue() (or any of the other methods that javax.servlet.http.Cookie class defines to retrieve other parameters) on that object to get the value of this particular cookie.

Cookie[] cookies = request.getCookies();
String cookieName = SAPCookie;
String defaultValue = 1;
for(int i=0; i<cookies.length; i++) }
      Cookie cookie=cookies[i];
      if (cookieName.equals(cookie.getName()))
        return(cookie.getValue());
    }
    return(defaultValue);
  }
