Actually I would love also to know a more sophisticated way to launch a java program, like being able to click on an icon that doesn't look like a cog in a window, but that's another matter. I'm more concerned about how I would run my program on a Mac. Any suggestions?
If you put your program into a single .jar file and put a manifest in it that says where the main() program is located, the jar file will start with a double click on Mac OS 10.2.8. It might not work on older versions of the operating system, though.
