Can I get the resource in a JAAS login module?

Question

G'day,
I am writing a custom JAAS login module for deplyment in Netweaver application server. I'd like to get information about the resource that is protected by that login module (specifically, the URL).
The HttpGetterCallback class does not provide this information. All I can get is the host name and port from the HTTP headers.
Is there any way to get the full URL of the resource within a login module?

G'day,
Note also that I tried using the WebCallback class, which has a getRequest() method that returns a HttpServletRequest.
But this callback seems to be ignored by the callback handler used in Netweaver AS, as the getRequest() method returns null, even though the login module is used to protect a servlet.
[ As an aside, I passed a custom callback to the CallbackHandler supplied by Netweaver AS, and the callbackHandler.handle() method did not throw UnsupportedCallbackException, which seems to be in violation of the JAAS standard ]
So ... HttpGetterCallback does not return resource URL information, and WebCallback is apparently ignored by the callback handler (which should really throw an exception here).
Are there any other ways to get the URL of the resource in a Netweaver AS login  module?
