I believe the UnsatisfiedLinkError means something else. It
typically means that the java runtime could not find a method
on a native library when it tried to make a call. In this case
the error is not that the java-gnome libraries could not be found
but that the gnome libraries were not initialized and loaded properly.
If you add the following line:
Program.initGnomeUI("DateEditDemo", "1.0", args);
just prior to the call to Gtk.init and include the Program
import your example will work.
