callbacks:

If this parameter specifies a reference to the WebSSOCallback object, session information is set and returned. If it specifies a class other than this one, the handle method of CallbackHandler specified in the constructor is called.

java.io.IOException:

This exception occurs in the handle method of CallbackHandler for each system.

javax.security.auth.callback.UnsupportedCallbackException:

This exception occurs when both of the following conditions coexist:

• A reference to CallbackHandler for each system is not specified in the constructor (when null is specified).
• This exception occurred in the handle method of CallbackHandler for each system.

Set a value for callbacks so that this value can be returned. This method does not return a value.
