gov.va.med.vistalink.security.CallbackHandlerSwing

GENERAL DESCRIPTION

public class CallbackHandlerSwing extends
java.lang.Object implements javax.security.auth.callback.CallbackHandler.

Implements the JAAS CallbackHandler interface. Use with the VistaLoginModule
to invoke a Swing-based interactive logon. Input values (access code, verify
code, division selection, and other "user input") are collected via a set of
GUI dialogs when this callback handler is used. To use:

1. Create an instance of CallbackHandlerSwing. No parameters are needed. 2.
Create the JAAS LoginContext instance, passing the instance of the callback
handler as one of the parameters. 3. Invoke the JAAS login context's login
method. The callback handler will invoke Swing dialogs to collect user input
wherever required for login.
