Also make sure you use the applet tag - NOT the object tag, that will save you some bytes
???
“Webstarted games’ code size will be determined with the JAR that Webstart uses to launch the game”
Starting an applet with webstart will gain even more bytes then (Yes, you can just do that.). But this is silly. The rule page doesnt state anywhere that the size of the html file is counted towards your file size. And well, as I said you can just start an applet through jws… and then its magically alright, huh?
