[FIXED] Not working on a Mac

[RobBuckley]

I've got an iMac Core Duo with Leopard installed. Try as I might, I can't get Jukes to launch. I have the latest version (4.1.1.39) and I've tried launching it by double-clicking the .jar file and by running the .sh script, but neither work - I always get the message "The jar file "jukes-4.1.1.39-app.jar" couldn't be launched. Check the Console for possible error messages."

I check the Console log and these are the results for the jar launcher

I note that the FAQ says "Does it run on Mac OS X?
Yes it does. On MacOSX, you don't even have to install a Java environment, since it comes with the operating system, so you can start using Jukes right away! Although only MacOSX 10.5 or higher come with Java 6. It will not run on 10.4 or under."

As far as I'm aware, Leopard doesn't come with Java 6 - there's a developer preview of Java SE 6 http://docs.info.apple.com/article.html?artnum=307208, but that won't run on my iMac. Is there a problem with Jukes or does it simply not run on a Mac (or at least my Mac)?

Unfortunately Apple has delayed Java 6 for the Mac for so long. It was supposed to be in Tiger and then they gauranteed it would be Leopard and they failed on both promises. It will only work on MacOSX once Apple releases Java 6 for it...if EVER.

Sorry.

It works on Mac OSX now that the Java 6 has been released!
