Windows Linux conflict - TrayIcon image not display in Linux

[Eranga]

Hi all,

I have create a TrayIcon and then add image and a pop-up menu into it as follows.

Code:

public void trayIconEventHandling()
    {
        TrayIcon trayIcon;
 
        if (SystemTray.isSupported()){
            SystemTray tray = SystemTray.getSystemTray();
            
         // I have to use this ActionEvent to exit the dialog as well
         // Exit from the complete application
            ActionListener exitListener = new ActionListener(){
                public void actionPerformed(ActionEvent e){
                    System.out.println("Exiting...");
                    System.exit(0);
                }
            };
            
        // Open the dialog in Actionevent
            ActionListener openDialogListner = new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    System.out.println("Open another Dialog here.");
                    new AboutWindow().setVisible(true);
                }
            };
            
        // Tray icon menu implimenting goes here
            PopupMenu popup = new PopupMenu();
            MenuItem defaultItem = new MenuItem("Exit");
            MenuItem openDlgItem = new MenuItem("About");
            MenuItem extartItem = new MenuItem("Others...");
            
            openDlgItem.setEnabled(false);
            
            defaultItem.addActionListener(exitListener);
            openDlgItem.addActionListener(openDialogListner);
            
            popup.add(defaultItem);
            popup.add(openDlgItem);
            popup.addSeparator();
            popup.add(extartItem);
 
            Image image = Toolkit.getDefaultToolkit().getImage("mytrayicon/RADAR.gif");
            trayIcon = new TrayIcon(image, "Pop-up", popup);
 
            ActionListener actionListener = new ActionListener(){
                public void actionPerformed(ActionEvent e){    
                    System.out.println("Main Dialog!");
 
                // Try to simply call the GUI here
                    mainWnd.setVisible(true);
                }
            };
            trayIcon.setImageAutoSize(true);
            trayIcon.addActionListener(actionListener);
            trayIcon.addMouseListener(mouseListener);
 
            try
            {
                tray.add(trayIcon);
            } 
            catch (AWTException e) 
            {
                System.err.println("TrayIcon could not be added.");
            }
        } 
        else{
            System.err.println("System tray is currently not supported.");
        }   
    }

My code working well on Windows, loaded the image correctly. But in Linux it don't.

As far as I know about Java, I believe my code is correct. Then why this is happened on Linux. Somebody can give me a hint that where I'm going wrong.

Important thing here is, Linux does not give any exception also.
