Class WebServiceAuthenticationHelper

java.lang.Object

au.org.ala.cas.client.WebServiceAuthenticationHelper

public class WebServiceAuthenticationHelper
extends Object

Helper class that authenticates user credentials prior to invoking a web service that requires authentication. Authentication is carried out during construction and the CAS generated Ticket Granting Ticket is saved for subsequent web service invocations.

Invoking a web service using the invoke() method involves obtaining a CAS service ticket which is then passed to the web service provider as a URI parameter. The web service provider application then obtains the user attributes via its CAS validation filter.
