Standalone SWT/JFace applications require the OSGi framework? [message #437511]

Hi all,

I'm working upon a SWT/JFace Eclipse 3.0RC1 standalone GUI and I've just
added a menu bar with a File/Quit menu item.

When I select the Quit option I receive this message:

java.lang.NoClassDefFoundError: org/osgi/framework/InvalidSyntaxException

at org.eclipse.jface.util.Policy.getDebugOption(Policy.java:100 )

Am I supposed to locate and download an OSGi implementation from IBM
(assuming it is appropriately licensed) or is this class dependency
spurious?

My menu bar instantiation is rudimentary:

public class GuiApplication extends ApplicationWindow {
...
protected MenuManager createMenuManager() {
MenuManager menu = new MenuManager("");
MenuManager file_menu = new MenuManager("&File");
MenuManager edit_menu = new MenuManager("&Edit");
MenuManager help_menu = new MenuManager("&Help");
menu.add(file_menu);
menu.add(edit_menu);
menu.add(help_menu);
file_menu.add(new QuitAction(this));
return menu;
}
...
}

public class QuitAction extends Action {
ApplicationWindow current_window;

public QuitAction (ApplicationWindow window) {
current_window = window;
this.setText("&Quit@Ctrl+Q");
}
public void run() {
current_window.close();
}
}

Thanks,
Adam

My follow up to:
java.lang.NoClassDefFoundError: org/osgi/framework/InvalidSyntaxException

I overlooked the jar available in
../eclipse/plugins/org.eclipse.osgi_3.0.0/osgi.jar

The jar contains org.osgi.* classes in addition to the usual Eclipse
org.eclipse.* classes.

Regards,
Adam

I'm not sure if this dependency was intentional on our part. I've filed Bug
67050 ("https://bugs.eclipse.org/bugs/show_bug.cgi?id=67050").

cheers,
