java maskeraiding as firefox - how?

this is a tough one, but theres got to be a way to do it. my program accesses urls, but when it tries google, google says
NO! IM GIVING U A 403!
because google doesn't like automated searches, it only wants browsers to visit google, not java programs.
the way it does this most likely is with the php variable $_SERVER['HTTP_USER_AGENT']
it tests for the browser type, and if its not one of the major browsers, it returns a 403.
i need my java program to know when it is given this request, and i need to learn how to send back any string i want, because then i can tell google that java is firefox, when its not.

uc.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727)"); // Will set IE user agent
got it, this may also be the solution to my previous post
