Cr-48 Java Help

Hey there!

Really love the site, been looking for a decent online IDE for a while in preparation for....

My brand new Cr-48! :D

However, i'm running into some problems.

I'm a (budding) java developer, and from what I understand how you would see how your code looks in the console is the "preview" button (I'm not really moving beyond basic text yet guys). Yet on my Cr-48 running Chrome OS (obviously) when I hit "preview", I get a blank box in the middle of the screen saying "missing plug-in". Now I'm just wondering what that box would be on a working set up. Is it flash? if so, I can tinker with my flash auto-play setting. Is it what JDK I have installed? Because I'm not sure exactly what iterations/forms/whatever of Java Chrome OS has at the moment, and I'd probably have to talk to some head honchos over at the dev forum to get a straight answer at this point.

Thanks for the help!
