user authorisation program

Hi 

I want to write a program using Jigsaw API to validate user-id/password.
The id and password would be entered on a web page and the data entered
compared with a database on a Jigsaw server.

Q. What classes would I need to use and what should the structure be
like?

Awaiting your response. Thanks.
