This will take some research on your part, and there are thousands of resources out there on the web. I would suggest using JQuery for this. Basically, user fills in their userid, hits a button (or something) that triggers the ajax call back to the server. On the server you have a CFC with a method to process the request. The ajax code on your page would have a 'success' handler that would put the info in the form once the request has completed properly.
