Well I didn’t.
This is because “Mac OS X is the only major consumer operating system that comes complete with a fully configured and ready-to-use Java runtime and development environment”. Taken from: http://developer.apple.com/java/.
To download/update Java for different versions of Mac OS X you will need to go to Apple’s Developer Connection site for Java.
(I need to install JDK 6 because of the new Java Desktop Features I’m using in my application)
Now, all I need is to figure out the Mac OS X version of my target users and I’m good to go.
Well that didn’t sound so easy to do.
