I'm new in eclipse programming. I'm trying to add a simple

I'm getting an error for the following code. Do you know
where is the bug?

<----->

import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.part.ViewPart;
import org.eclipse.swt.widgets.Canvas;

import org.eclipse.draw2d.*;

public class LabelView extends ViewPart {
=

Canvas canvas;
=

public LabelView() {
super();
}
=

public void setFocus() {
} =

=

public void createPartControl(Composite parent) {
=

canvas =3D new Canvas(parent,0);
LightweightSystem lws =3D new LightweightSystem(canvas);
IFigure panel =3D new Figure();
lws.setContents(panel);

Shape ellipse =3D new Ellipse();
ellipse.setBackgroundColor(ColorConstants.yellow);

panel.add(ellipse);
=

}
}

Can you tell us what the error is?
In your runtime workbench, go to Windows -> Show View -> Other -> PDE
Runtime -> Error Log

So, apparently, the problem is not in your code, but in your setup. Have
you added the drawd2 plugin as required in your plugin.xml?
