How do I put a Java app in the system tray?

Question

I have a little control-panel, just a little application that I made. I would like to minimize/put the control-panel up/down with the systemicons, together with battery life, date, networks etc.

Anyone that can give me a clue, link to a tutorial or something to read?

As of Java 6, this is supported in the SystemTray and TrayIcon classes. SystemTray has a pretty extensive example in its Javadocs:

TrayIcon trayIcon = null; if (SystemTray.isSupported()) {     // get the SystemTray instance     SystemTray tray = SystemTray.getSystemTray();     // load an image     Image image = Toolkit.getDefaultToolkit().getImage("your_image/path_here.gif");     // create a action listener to listen for default action executed on the tray icon     ActionListener listener = new ActionListener() {         public void actionPerformed(ActionEvent e) {             // execute default action of the application             // ...         }     };     // create a popup menu     PopupMenu popup = new PopupMenu();     // create menu item for the default action     MenuItem defaultItem = new MenuItem(...);     defaultItem.addActionListener(listener);     popup.add(defaultItem);     /// ... add other items     // construct a TrayIcon     trayIcon = new TrayIcon(image, "Tray Demo", popup);     // set the TrayIcon properties     trayIcon.addActionListener(listener);     // ...     // add the tray image     try {         tray.add(trayIcon);     } catch (AWTException e) {         System.err.println(e);     }     // ... } else {     // disable tray option in your application or     // perform other actions     ... } // ... // some time later // the application state has changed - update the image if (trayIcon != null) {     trayIcon.setImage(updatedImage); } // ...

It's very simple

import java.awt.*; import java.awt.event.*; import javax.swing.JOptionPane;  public class SystemTrayDemo{  //start of main method public static void main(String []args){     //checking for support     if(!SystemTray.isSupported()){         System.out.println("System tray is not supported !!! ");         return ;     }     //get the systemTray of the system     SystemTray systemTray = SystemTray.getSystemTray();      //get default toolkit     //Toolkit toolkit = Toolkit.getDefaultToolkit();     //get image      //Toolkit.getDefaultToolkit().getImage("src/resources/busylogo.jpg");     Image image = Toolkit.getDefaultToolkit().getImage("src/images/1.gif");      //popupmenu     PopupMenu trayPopupMenu = new PopupMenu();      //1t menuitem for popupmenu     MenuItem action = new MenuItem("Action");     action.addActionListener(new ActionListener() {         @Override         public void actionPerformed(ActionEvent e) {             JOptionPane.showMessageDialog(null, "Action Clicked");                   }     });          trayPopupMenu.add(action);      //2nd menuitem of popupmenu     MenuItem close = new MenuItem("Close");     close.addActionListener(new ActionListener() {         @Override         public void actionPerformed(ActionEvent e) {             System.exit(0);                      }     });     trayPopupMenu.add(close);      //setting tray icon     TrayIcon trayIcon = new TrayIcon(image, "SystemTray Demo", trayPopupMenu);     //adjust to default size as per system recommendation      trayIcon.setImageAutoSize(true);      try{         systemTray.add(trayIcon);     }catch(AWTException awtException){         awtException.printStackTrace();     }     System.out.println("end of main");  }//end of main  }//end of class 

Set appropriate path for image and then run the program. t.y. :)
