Re: Building MRJAdapter on Leopard

Let me put the question the other way...

Is there a method to have a "normal" application menu (with Quit not
in the original menu but in the application menu, and a About item in
the same menu) without using MRJAdapter ?


Apple puts the "Quit", "Preferences" and "About" items in the application menu. They are there in a Mac Java app regardless of what other software you use. Keeping the items out of other menus (e.g. Quit/Exit in the File menu) is up to your code. By default Apple hooks up "Quit" to System.exit. Apple provides APIs to hook listeners to these menu items. See the Apple extensions JavaDoc:

http://developer.apple.com/documentation/Java/Reference/1.5.0/ appledoc/api/index.html

Implementing this in a manner that works on all platforms, regardless of the existence of the Apple extensions in the classpath is not rocket science, but does require some attention to detail and an understanding of how class loading works (and thus how it fails when the extensions are not present). MRJAdapter encapsulates those details. Apple also provides sample code on using the extensions, which can provide some insight into these details, if not a fully abstracted solution:
