Thanks to Andreas Tobler I was able to follow his lead and get GCJ with Swing/AWT-enabled running on Mac OS X. As promised, I wrote an article describing the steps we went through to get it working. http://www.bestweb.net/~john3g/gcj_osx/gcj_on_osx_gui.html If anyone spots any errors or can offer any corrections, I'd be much obliged. :) Thanks, ---John
