public class JAASCallbackHandler extends Object implements CallbackHandler
Implementation of the JAAS CallbackHandler interface,
used to negotiate delivery of the username and credentials that were
specified to our constructor. No interaction with the user is required
(or possible).
This CallbackHandler will pre-digest the supplied
password, if required by the <Realm> element in
server.xml.
At present, JAASCallbackHandler knows how to handle callbacks of
type javax.security.auth.callback.NameCallback and
javax.security.auth.callback.PasswordCallback.
