Direct Known Subclasses:

public class CallbackHandlerSwing
extends Object

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") is collected via a set of GUI dialogs when this callback handler is used.

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.

For example:

String cfgName = "RpcSampleServer";

// create the callback handler
CallbackHandlerSwing cbhSwing = new CallbackHandlerSwing(myFrame);

// create the LoginContext
loginContext = new LoginContext(cfgName, cbhSwing);

// login to server
loginContext.login();
