No need customized the class. Hope, the following code will solve your problem.

public class Sample extends UiApplication {
public Sample() {
    pushScreen(new SampleScreen());
}
public static void main(String[] args) {
    Sample sample = new Sample();
    sample.enterEventDispatcher();
}
private static class SampleScreen extends MainScreen {

    public SampleScreen() {

        VerticalFieldManager vfManager = new VerticalFieldManager(Field.FIELD_HCENTER);
        vfManager.add(new LabelField("Test Label"));
        vfManager.add(new BitmapField(Bitmap.getBitmapResource("image.png")));
        vfManager.setBorder(BorderFactory.createRoundedBorder(
                new XYEdges(5, 5, 5, 5),
                Color.ORANGE,
                Border.STYLE_SOLID
            ));
        add(vfManager);
    }
}

}

Hi,

It should be noted that the BorderFactory class wasn't added until JDE 4.6.0. If you are your application on a older JDE platform then you will have to override the vertical manager's paint method to draw the border.
