Change:

private final static String LOGIN = "xxxxx@chat.facebook.com";

To:

private final static String LOGIN = "xxxxx";

Well not exactly ;). You get the idea though..

XMPP spec for facebook does not include the @server.here for login. Either include it in your username string or delete your server string entirely.

Facebook login is different:
