Just read the error message - Java can't find a class definition for
the class java.util.prefs.Preferences. This class wasn't introduced
until Java 1.4, and there is no currently shipping Java 1.4
implementation for Mac OS X, just a developer preview. If you want to
require Java 1.4, then you need to specify it at runtime. I don't
think I'm allowed to say any more about this but you should be able to
get more help on the NDAed list.
If you're writing a Cocoa-Java application, you may want to
investigate NSUserDefaults instead.
