Downloading JARs

I'm trying to download this java applet so's I can play it offline:

http://dan-ball.jp/en/javagame/dust/

So I downloaded the .jar, and then in the same directory made an HTML file into which I copy-pasted the <APPLET> tag from the original web page. I also downloaded any .js files linked to by that webpage just in case.

But when I try and run the applet by opening the HTML file in firefox, it throws null pointer exceptions. What's going on here, /prog/?

Play a real game instead, like Super Mario Galaxy 2, currently the highest rated game of all time.^[1]

This list seems biased. I played Super Mario Galaxy once and it was atrocious.

>>3
Same, except I played it more than once and it was atrocious each time.

Also, OP here still hoping for some answers.

>>4
Is there anything to do with some kind of .j* page on the server? If there is, you probably won't get it to work.

>>5
.j*? What, as in .j followed by anything?

Now that you mention it, the document Head does link to two JavaScript files with weird extensions:

"/java.js?8" and "/javagame/dust/dust.js?24"

Why, what are they?

Just realized you were probably talking about the Java stack trace. No, it doesn't mention anything like that:

I meant as in some server-side java stuff that the applet might talk to. The 'weird extensions' are just server parameters for the otherwise-ordinary javascript files.

This is /prog/, not /warezkindergarten/. However in hopes you'll go away, I'd start with getting a network trace (with clean caches) just to see what you're up against. With a bit of luck it'll be only static resources.
