Oops, I meant to reply to the list but replied to Will directly. Here is a copy of my response to Will's question in case anyone else is interested in a solution as well... > A client of mine has a Java application for running live Auctions that runs > beautifully on Windows and works in concert with a FileMaker Pro database system that I've been helping him develop for a couple of years now. I'm interested if anyone has a tip on how to get the Java app running on Mac OS > X. Hello Will, I hope this article is what you are looking for. :) Tailoring Java Applications for Mac OS X :: Launching Java Applications http://developer.apple.com/technotes/tn/tn2042.html#Section2_6 I have a project that involves java game development and I have a Windows laptop I test on and a Ruby iMac that I also test on so this topic came up for me recently. I found this whole article very useful with regard to developing Java apps for use on Macs as well as Window machines. :) Good luck! -Michael McIntosh
