What you actually lack is a parent component to show your PopupMenu. One way to achieve this, is to use an "invisible" frame (actually it is visible but with 0-bounds and undecorated, so you can't see it) like this:

import java.awt.AWTException;
import java.awt.CheckboxMenuItem;
import java.awt.Frame;
import java.awt.Menu;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.net.MalformedURLException;
import java.net.URL;

public class MyTaskTray {
    public static void main(String arg[]) throws MalformedURLException {
        final Frame frame = new Frame("");
        frame.setUndecorated(true);
        // Check the SystemTray is supported
        if (!SystemTray.isSupported()) {
            System.out.println("SystemTray is not supported");
            return;
        }
        final TrayIcon trayIcon = new TrayIcon(Toolkit.getDefaultToolkit().getImage(
                new URL("http://home.comcast.net/~supportcd/Icons/Java_Required.jpg")), "Library Drop");
        final SystemTray tray = SystemTray.getSystemTray();

        // Create a pop-up menu components
        final PopupMenu popup = createPopupMenu();
        trayIcon.setPopupMenu(popup);
        trayIcon.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (e.getButton() == MouseEvent.BUTTON1) {
                    frame.add(popup);
                    popup.show(frame, e.getXOnScreen(), e.getYOnScreen());
                }
            }
        });
        try {
            frame.setResizable(false);
            frame.setVisible(true);
            tray.add(trayIcon);
        } catch (AWTException e) {
            System.out.println("TrayIcon could not be added.");
        }

    }

    protected static PopupMenu createPopupMenu() {
        final PopupMenu popup = new PopupMenu();
        MenuItem aboutItem = new MenuItem("About");
        CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size");
        CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip");
        Menu displayMenu = new Menu("Display");
        MenuItem errorItem = new MenuItem("Error");
        MenuItem warningItem = new MenuItem("Warning");
        MenuItem infoItem = new MenuItem("Info");
        MenuItem noneItem = new MenuItem("None");
        MenuItem exitItem = new MenuItem("Exit");
        // Add components to pop-up menu
        popup.add(aboutItem);
        popup.addSeparator();
        popup.add(cb1);
        popup.add(cb2);
        popup.addSeparator();
        popup.add(displayMenu);
        displayMenu.add(errorItem);
        displayMenu.add(warningItem);
        displayMenu.add(infoItem);
        displayMenu.add(noneItem);
        popup.add(exitItem);
        return popup;
    }
}

As of Java 1.7, you can add the following line to remove the application bar from the taskbar:

frame.setType(Type.UTILITY);

This should work:

trayIcon.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent e) {
        JOptionPane.showMessageDialog(null, "This shows after a left-click on tray icon");
    }
});

Override any other methods if you want a different kind of event (not just the click event from the example above).

I think you are looking for a MouseListener which you will add to your TrayIcon and will activate when a button on the mouse is clicked,moved etc. To get it to operate for left clicks only have a look at the ButtonMasks on MouseEvent (BUTTON1) being for left mouse clicks.

You could read the official tutorial at http://docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.html or check out http://weblogs.java.net/blog/ixmal/archive/2006/05/using_jpopupmen.html for a solution to use a jpopuomenu instead

you can add ActionListener to the TrayIcon, mouse double_click can showing JOptionPane 

trayIcon.addActionListener(new ActionListener() {

   @Override
   public void actionPerformed(ActionEvent e) {
       JOptionPane.showMessageDialog(null, "This dialog box is run from System Tray");
   }
});
