First of all, just let me say that I apologize if I misuse any Java terminology. It's not my field of expertise - I'm an Obj-C/Cocoa guy, so some Java stuff gets me completely lost. I'm trying to make a Java app that I use frequently a little more Mac friendly. Normally, it's just a bare .jar and so lacks many things, such as a proper app name, dock icon, and Mac menubar usage. I still have a copy of the Jar Bundler included with Xcode 3. The bundles it produces work nicely for the most part, but it has a problem with this particular jar file. For whatever reason, the Use Macintosh Menu Bar option doesn't work. In fact, it's completely ignored, and the app's menus remain attached to its window. I do not have access to the source. What could cause the menubar option to fail? Is there anything I can do without first acquiring the source? P.S. It's no big deal if it's not possible, but is there some way I can force the application to use native (or closer to native) file dialogs instead of the mediocre-at-best standard Java ones?
