[Java-gnome-developer] java.lang.UnsatisfiedLinkError: gnome_date_edit_new

[Jason P. <ja...@wi...>]

Hi everyone,

I recently installed java-gnome(had a problem building because I didn't
have ANT installed) compiled and ran the example code.  Everything went
well.  I am interested in the DateEdit class. I edited the
EntryDemo.java example....

http://java-gnome.sourceforge.net/docs/GNOME-tutorial/c688.html#ENTRY

to the following....


import org.gnu.gnome.DateEdit;
import org.gnu.gtk.Gtk;
import org.gnu.gtk.HBox;
import org.gnu.gtk.Widget;
import org.gnu.gtk.Window;
import org.gnu.gtk.WindowType;
import org.gnu.gtk.event.LifeCycleEvent;
import org.gnu.gtk.event.LifeCycleListener;
import java.util.Date;
public class DateEditDemo {

	public static void main(String[] args) {
		boolean thetruth = true;
		Gtk.init(args);
		Window w = new Window(WindowType.TOPLEVEL);
		w.addListener(new LifeCycleListener() {
			public void lifeCycleEvent(LifeCycleEvent event) {
				if (event.isOfType(LifeCycleEvent.Type.DESTROY) || 
					event.isOfType(LifeCycleEvent.Type.DELETE)) {
					Gtk.mainQuit();
				}
			}
		});
		w.setDefaultSize(200,200);
		w.setBorderWidth(5);
		w.setTitle("DateEdit Demo!!!");
		w.add(new DateEdit(new Date(), thetruth, thetruth ));
		w.showAll();
		Gtk.main();
	}
}


the code compiles fine and when launched I get the following....


Exception in thread "main" java.lang.UnsatisfiedLinkError:
gnome_date_edit_new
        at org.gnu.gnome.DateEdit.gnome_date_edit_new(Native Method)
        at org.gnu.gnome.DateEdit.<init>(DateEdit.java:52)
        at DateEditDemo.main(DateEditDemo.java:27)

I have only worked a little bit with Java Native Interface so I don't
know where to start. A little research suggests the following in
DateEdit.java...

native static final protected int gnome_date_edit_new(long the_time,
boolean show_time, boolean use_24_format);

should be changed to the following along with the supporting code but I
am not sure....

native static final protected int gnome_date_edit_new(int the_time, int
show_time, int use_24_format);

gnome_date_edit_new suggests that "the_time" in an unsigned long (32
bits) not java long (64 bits) and the show_time and use_24_format are
int not boolean.  But again I am very new to JNI.. I made the changes
but got the same error UnsatisfiedLinkError


I'm I way off?

Thanks,
