Hi,
I need to get the page ID for one of the facebook pages I manage. I would like to use it to get a "page access token". But the result is empty.

String appId = "";
String appSecret = "";
String SUCCESS_URL = "https://localhost/";

String newValue = ""; // Return url from facebook after successful login

String code = newValue.substring(codeOffset + "code=".length());

DefaultFacebookClient facebookClient = new DefaultFacebookClient(Version.LATEST);
AccessToken accessToken = facebookClient.obtainUserAccessToken(appId, appSecret, SUCCESS_URL, code);

AccessToken extendedAccessToken = facebookClient.obtainExtendedAccessToken(appId, appSecret, accessToken.getAccessToken());
String extendedToken = extendedAccessToken.getAccessToken();

FacebookClient facebookClient2 = new DefaultFacebookClient(extendedToken, Version.LATEST);
User user = facebookClient2.fetchObject("me", User.class);

List ids = user.getIdsForPages(); // Is empty

String pageAccessToken = "";

Does anyone know How I can fix this?

Thank you
