DeObfuscating and Decompiling

[Lukeidiot]

is it possible to deobfuscate/decompile this applet?

http://www.runescape.com/loginapplet...&dest=index.ws

<applet class="loginapplet" archive="loginapplet-4da9dce0-1119942563.jar" code="loginapplet.class" height="200" width="400" mayscript>
<param name="cabbase" value="loginapplet-26fb3f34.cab?cb=668995011">

Decompiling java is easy to do, but deobfuscation... If you really want it, you can do it.. it won't be a journey though.
BTW it's illegal most of the times
