UltraMixer/JarBundler: JarBundler is a feature-rich Ant task which will create a Mac OS X application bundle from a list of Jar files and a main class name. You can add an Icon resource, set various Mac OS X native look-and-feel bells and whistles, and maintain your application bundles as part of your normal build and release cycle.
