Hi,
I tried to test the tutoriel from
developerWork with Eclipse M8 :
"Using the Eclipse GUI outside the Eclipse Workbench, Part 1: Using JFace
and SWT in stand-alone mode"
I have got this error message :

Exception in thread "main"
Here is the code :
import java.io.*;
import org.eclipse.jface.viewers.*;
import org.eclipse.jface.window.*;
import org.eclipse.swt.widgets.*;
public class Explorer extends ApplicationWindow {
public Explorer() {
super(null);
}
protected Control createContents(Composite parent) {
TreeViewer tv = new TreeViewer(parent);
tv.setContentProvider(new FileTreeContenProvider());
tv.setInput(new File("C:\\"));
return tv.getTree();
}
public static void main(String[] args) {
Explorer w = new Explorer();
w.setBlockOnOpen(true);
w.open();
Display.getCurrent().dispose();
}
}
import java.io.*;
import org.eclipse.jface.viewers.*;
public class FileTreeContenProvider implements ITreeContentProvider {
public Object[] getChildren(Object element) {
Object[] kids = ((File)element).listFiles();
return kids == null ? new Object[0] : kids;
}
public Object[] getElements(Object element) {
return getChildren(element);
}
public boolean hasChildren(Object element) {
return getChildren(element).length > 0;
}
public Object getParent(Object element) {
return ((File)element).getParent();
}
public void dispose() {}
public void inputChanged(Viewer viewer, Object old_input, Object
new_input) {}
}
My classpath is :
- EclipseHome\plugins\org...\jFace.jar
- EclipseHome\plugins\org ...\swt.jar
- EclipseHome\plugins\org.eclipse.ui\workbench_3.0.0\workbench .jar
- EclipseHome\plugins\org.eclipse.core.runtime_3.0.0\runtime.j ar
>>> I did not find org.eclipse.runtime_2.1.0\runtime.jar which is
required !!!
Thank for your help,
Regards,
A.Didiot
