Interface Summary

Interface Summary
Callback	Implementations of this interface are passed to a {@link CallbackHandler}, allowing underlying security services the ability to interact with a calling application to retrieve specific authentication data such as usernames and passwords, or to display certain information, such as error and warning messages. `Callback` implementations do not retrieve or display the information requested by underlying security services.
CallbackHandler	An application implements a `CallbackHandler` and passes it to underlying security services so that they may interact with the application to retrieve specific authentication data, such as usernames and passwords, or to display certain information, such as error and warning messages. `CallbackHandler`s are implemented in an application-dependent fashion.

PasswordCallback	Underlying security services instantiate and pass a `PasswordCallback` to the `handle()` method of a {@link CallbackHandler} to retrieve password information.
TextInputCallback	Underlying security services instantiate and pass a `TextInputCallback` to the `handle()` method of a {@link CallbackHandler} to retrieve generic text information.
TextOutputCallback	Underlying security services instantiate and pass a `TextOutputCallback` to the `handle()` method of a {@link CallbackHandler} to display information messages, warning messages and error messages.

Exception Summary
