Ok, I've installed Kubuntu (Mlord's constant praising helped with that decision!) and now want to try running JEmplode. I've downloaded the lastest Jemplode.jar (70) but when I click on the file I brings up the ARK extraction program. I've looked at the Synapic Package Manager and think I have Java installed. Do I need to download it directly from java.com? If so how do I install a RPM on Kubuntu? Thanks!
The ubuntu forums seem to be down...

P.S. I've got other Linux related questions if anyones to help!
