Class AuthNFilter

java.lang.Object
  org.eclipse.higgins.rp.servlet.server.AuthNFilter

All Implemented Interfaces:

javax.servlet.Filter

public class AuthNFilter
extends Object
implements javax.servlet.Filter

Authentication filter This is an authentication filter for relying party applications. The filter checks to see if a token is found in the session (indicating that a sucessful authentication has already taken place.) The filter and the web pages that require authentication are specified in the web.xml file for the application. The URL of the protected resource is invoked a few times during the authentication process. Each time the authenticaton process is in a different state. The filter sets the initial authentication state. The state is advanced inside the invoker class.
