Answer 1

The following code will probably show the cause of your problem, the opacity of the view.
import java.awt.Color;
import java.awt.event.ActionEvent;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.JCheckBoxMenuItem;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenuBar;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
public class BackgroundOnScrollPane {
    public static void main(String[] args) {
     SwingUtilities.invokeLater(new Runnable() {
         @Override
         public void run() {
          JFrame frame = new JFrame("Test back ground");
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          final JLabel content = new JLabel(
               "This is the content of the scroll pane", JLabel.CENTER);
          content.setOpaque(true);
          JScrollPane scrollPane = new JScrollPane(content);
          scrollPane.getViewport().setBackground(Color.PINK);
          frame.add(scrollPane);
          frame.setJMenuBar(new JMenuBar());
          frame.getJMenuBar().add(
               new JCheckBoxMenuItem(new AbstractAction(
                    "Content opaque") {
                   private static final long serialVersionUID = 1L;
                    this.putValue(Action.SELECTED_KEY, content
                         .isOpaque());
                   @Override
                   public void actionPerformed(ActionEvent e) {
                    content.setOpaque((Boolean) this
                         .getValue(Action.SELECTED_KEY));
                    content.repaint();
          frame.setSize(200, 200);
          frame.setLocationRelativeTo(null);
          frame.setVisible(true);
}Piet
