com.spotfire.server.jaas.util.AutoCallbackHandler

All Implemented Interfaces:

CallbackHandler

public class AutoCallbackHandler
extends Object
implements CallbackHandler

The AutoCallbackHandler is a utility class that can be used by all JAAS clients. It automatically handles Callback processing without requiring any user interaction, which makes it suitable for web application environments, where the user interaction has special requirements.

The constructor takes one username and one password argument. The username is used to set the name property of a NameCallback and the password is used to set the password property of a PasswordCallback. Both constructor arguments may be null.

The supported Callback implementations are NameCallback and PasswordCallback. The handle throws an UnsupportedCallbackException for all other Callback classes.
