Losing JToolTips when adding to JScrollPane

Question

I'm using a large ImageIcon as a JLabel in a JFrame, with other small JLabels over top of it. I've added tool tips to the smaller jlabels, and everything looks ok, and I get the jtooltips to fire normally. The problem is that the image is too large for the screen, so I need to be able to scroll it.
public class GelFrame extends JFrame {
    public GelFrame(.......) {
      // add main gel image
      JLabel GEL = new JLabel(new ImageIcon(image));
      GEL.setBounds(0,0,width,height);
      getContentPane().add(GEL);
      // add the smaller JLabels here
      ArrayList spot = new ArrayList();
      for(int i=0; i<passedArrayList.size(); i++) {
        spot = (ArrayList)passedArrayList.get(i);
        System.out.println("protein: "+(String)spot.get(0));
        int x = ((Integer)spot.get(1)).intValue();
        int y = ((Integer)spot.get(2)).intValue();
        JLabel label = new JLabel();
        label.setBackground(new Color(000,255,000));
        // set the bounds of the new label
        label.setBounds(x+1, y+1, 3,3);
        System.out.println("** creating label with bounds: "+x+", "+y+", 3, 3");
        // add the tool tip text to the jlabel
        label.setToolTipText((String)spot.get(0));
        // add to the JFrame
        getContentPane().add(label);
}When I add this JFrame to a JScrollPane, I get the proper scrolling, but I lose the jtooltips.

Thanks for the reply!
I made the suggested changes, and I'm still not able to see the jtooltips. Is there something about the viewport that gets in the way, or covers up the JPanel? Should it matter when I add the tooltip'd jlabels to the JPanel?
