Mac Java - how to use a different JVM on Mac OS/X 10.4

Mac Java FAQ: I'm currently using Mac OS/X 10.4 with Java 1.5.x. But, for a certain application I need to use a previous version of Java, which I can see is actually installed on the hard drive. Can I use this older Java JVM on Mac OS X 10.4?

Answer: Yes, I was able to do this. The hardest part about this is finding where the previous Java version is installed. There are probably easier ways to do it, but I ended up using the Mac mdfind command, which is the command-line version of Spotlight.

Mon, Feb 27, 2006 (Making the switch)

Some time in the very near future I will make the switch. Yesterday I placed an order for a MacBook Pro, and now I anxiously await its arrival.

Before discussing my reasons for making the switch, let me first state that I am not currently an iPod or iTunes user. I may get to those things eventually, but for now those things are non factors, and what I'm most interested in is developing new software for customers, and designing new software systems.
