How can i get the runescape webclient to work on my own website

So basically im trying to get the runescape web client to run in my own website so that i can play it at work without having to use a proxy

ive tried using the jagexappletviewer.jar with the java arguments from the prm file and wrapping it in html, but i get java.lang.reflect.Invocation.Target.Exception error

Anybody have any solutions?

Thanks for any help!

I am willing to pay $25 via PayPal for a solution, another way ive been trying to get this to work is through a reverse proxy on my server, but runescape checks the url its being loaded from using getdocumentbase(),
is there a way to spoof this?
