JAASCallbackHandler

public class JAASCallbackHandler implements CallbackHandler(Code)

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.
