How can I run a Windows GUI application on as a service?
I have added code for enable SystemTrayIcon for Windows 7. It is working fine with NetBeans application mode, while I am executing the application in windows services mode it is not working. Please find below code for your reference.
if (!java.awt.SystemTray.isSupported()) {    
                    System.out.println("SystemTray is not supported");    
                return;    
            }    
                final PopupMenu popup = new PopupMenu();    
            Image img1 = new ImageIcon(DataReporter.class.getResource("/lookandfeel/data/xear_appIcon_16.png")).getImage();    
            ImageIcon icon = new ImageIcon(img1);    
                final TrayIcon trayIcon = new TrayIcon(icon.getImage());    
                trayIcon.setToolTip(DataReporterProps.softwareDescriptionText);
                final java.awt.SystemTray tray = java.awt.SystemTray.getSystemTray();    
                MenuItem aboutItem = new MenuItem("About");    
                popup.add(aboutItem);
                trayIcon.setPopupMenu(popup);    
                try {    
                tray.add(trayIcon);    
            } catch (AWTException e) {    
                System.out.println("Cannot add the TrayIcon!");    
            }
Please let me know if any code wants to be added for triggering in windows service mode.
