The Dialog during Authentication process. In general, for being able to deal with the Authentication within a custom made application, it is requiered to to create an object that implements the interface Authenticator. The function : String authenticate(String request) throws AuthenticationException; Will have to be implemented, and it is the one that will be called when Broker will request all user interaction. It will receive a String "Request" in XML, and the function will have to return a String "Reply" in XML. In Windows platforms, if no authenticator is passed to the Object, broker GUI wll perform the Authentication dialog.
