Flickering problem in JPanel

Question

hello, i'm sorry this might be a too popular topic, but my problem is a little different.
I have a JPanel which is newed with an Image, and I move it (using setBounds()) in my application when a button is clicked. It flicked badly ... after I've done some research, then i use the setDoubleBuffered(true), still the same problem, isn't the API used to remove the flickering by doubled buffering? I'm using JDK 1.3.1, FYI.
could anyone throw me some lights on this? greatly appreciate it ..
Steve

Thanks for the prompt reply, i extract those code related ... sorry I was wrong in my previous post that this is a JLabel, not a JPanel.
The logic is pretty easy, everytime a button is clicked, I draw a JLabel at a different positioin (we also need to new it with an ImageIcon if it's the first time), that's it. but the problem is it flickered badly, and setDoubleBuffered(true) doesn't solve this problem as I expect.
Thanks for any comment.
public class MainView extends JLayeredPane
public void actionPerformed(ActionEvent e) {  // when a button is clicked     
if (first) { // if this is the first time, do the JLabel initialization
bottomPicLabel = new JLabel(bottomViewImage.getImage());
bottomPicLabel.setDoubleBuffered(true);
add(bottomPicLabel, BOTTOM_LAYER);
int bottomWidth = bottomViewImage.getEndX() - bottomViewImage.getStartX();
int bottomHeight = bottomViewImage.getEndY() - bottomViewImage.getStartY();
     // draw at a different place
bottomPicLabel.setBounds(
bottomViewImage.getStartX(),
bottomViewImage.getStartY(),
bottomWidth,
bottomHeight
}
