Transparency for JTabbedPane doesn't work with java version 1.5 .......

Question

Hi all,
I have a tabbed pane to which i add a panel. Both tabbed pane and panel are set opaque(setOpaque(false)) and i set background image for main container. It works fine in java version 1.4.2_04 showing all the panels and tabbedpane transparent. But when it run in version jdk1.5 the transparency effect goes off.
what is the problem? how to fix it up? please help....
here below is the code. Take any jpg image as background.jpg.
import java.awt.*;
import javax.swing.*;
import java.awt.color.*;
public class Test extends JDialog {
     float[] white = {.99f, .99f, .99f};
     public Test() {
          UIManager.put("TabbedPane.selected",
               new Color(ColorSpace.getInstance(ColorSpace.CS_sRGB), white, .0f));
          JTabbedPane tabbedPane = new JTabbedPane();
          Color COLOR_WHITE_TRANSPARENT_VAL = new Color(
               ColorSpace.getInstance(ColorSpace.CS_sRGB), white, 0.0f);
          tabbedPane.setBackground(COLOR_WHITE_TRANSPARENT_VAL);
          tabbedPane.setOpaque(false);
          JPanel p1 = new JPanel();
          p1.setOpaque(false);
          tabbedPane.add(p1, "Tab 1");
          // panel for displaying background image
          JPanel backPanel = new JPanel(new BorderLayout()) {
               ImageIcon img = new ImageIcon("background.jpg");
               public void paintComponent(Graphics g) {
                    Dimension d = getSize();
                    g.drawImage(img.getImage(),
                         0, 0, d.width, d.height, null);
                    setOpaque( false );
                    super.paintComponent(g);
          backPanel.setLayout(new BorderLayout());
          backPanel.add(tabbedPane, BorderLayout.CENTER);
          backPanel.setOpaque(false);
          getContentPane().setLayout(new BorderLayout());
          getContentPane().add(backPanel);
          setSize(300, 300);
          setVisible(true);
     public static void main(String[] args) {
          Test test = new Test();

Hi Reneto,
We had the same problem in our project where-in we asked BASIS team to install the lower version of JAVA 1.42..
No proper document from SAP for using lower version of JAVA.
I hope this helps.
