How can I change the Dock Icon of a program, in Java, on the Macintosh platform? I have heard about using Apple's Java library (that provides some sort of extra support on the Mac platform), but I have yet to find some actual examples.

While I'm not sure how to change it at runtime, you can set at the command line your Dock icon using the -Xdock:icon option, like:

 >java -Xdock:icon=/path/myIcon.png myApp

This article has lots of useful little info about bringing java apps to Mac, and you may be interested looking at the utilities and tools for Mac listed here, as well as deployment options listed here (the last link is especially useful if you want to go down the Java Webstart route).
