Linux with Java (-jar)?

[Draekal]

Hey guys I've finally switched to Linux, and I have to say I love it. One thing thats really beating me up is not being able to play Istaria however.

So for all you Linux users out there, I need help. O.O

1.) I installed Wine, and the needed apps for Istaria.
2.) I installed Java (JDK)
3.) I installed Istaria.
4.) I attempted to run istaria using the command...

java -jar launcher.jar

At this step it finally started up and let me log in. I showed my character and everything. I press the play button and I get a blank output, and nothing happens.

Anyone have an idea of what I should do?

Thanks,
Draekal

EDIT: When it shows a blank output, this is what I meant.
