使用什么技术将systray前端编写到webapp？

we have an internal webapplication running on tomcat, build on Spring. The webapplication front-end is build with Flex.
I would like to create a cross-platform systray application that allows to go the home page of the application and displays alerts when certain things happen in the server.

我们有一个在tomcat上运行的内部web应用程序,基于Spring构建。 Web应用程序前端是使用Flex构建的。我想创建一个跨平台的系统托盘应用程序,它允许进入应用程序的主页,并在服务器中发生某些事情时显示警报。

What would you think is the best technology for:

你认为最好的技术是什么:

The systray itself? Java Swing?

系统托盘本身? Java Swing?

Communication between the server and the systray? Webservice? RSS feed? Spring remoting? JMX Notifications?

服务器和系统之间的通信?网络服务? RSS订阅? Spring remoting? JMX通知?

If you want to stay with Java you have two options:

如果您想继续使用Java,您有两种选择:

Use Swing/AWT. Make sure you are using Java 6 and above (you can install it with your application), since it has support for system tray (from the API):

使用Swing / AWT。确保您使用的是Java 6及更高版本(您可以将其与您的应用程序一起安装),因为它支持系统托盘(来自API):

TrayIcon trayIcon = null;
if (SystemTray.isSupported()) {
    // get the SystemTray instance
    SystemTray tray = SystemTray.getSystemTray();
    // load an image
    Image image = Toolkit.getDefaultToolkit.getImage("");
    // 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);
}
// ...

Use SWT/JFace. Here is an example (taken from here):

使用SWT / JFace。这是一个例子(取自这里):

public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    Image image = new Image(display, 16, 16);
    final Tray tray = display.getSystemTray();
    if (tray == null) {
        System.out.println("The system tray is not available");
    } else {
        final TrayItem item = new TrayItem(tray, SWT.NONE);
        item.setToolTipText("SWT TrayItem");
        item.addListener(SWT.Show, new Listener() {
            public void handleEvent(Event event) {
                System.out.println("show");
            }
        });
        item.addListener(SWT.Hide, new Listener() {
            public void handleEvent(Event event) {
                System.out.println("hide");
            }
        });
        item.addListener(SWT.Selection, new Listener() {
            public void handleEvent(Event event) {
                System.out.println("selection");
            }
        });
        item.addListener(SWT.DefaultSelection, new Listener() {
            public void handleEvent(Event event) {
                System.out.println("default selection");
            }
        });
        final Menu menu = new Menu(shell, SWT.POP_UP);
        for (int i = 0; i < 8; i++) {
            MenuItem mi = new MenuItem(menu, SWT.PUSH);
            mi.setText("Item" + i);
            mi.addListener(SWT.Selection, new Listener() {
                public void handleEvent(Event event) {
                    System.out.println("selection " + event.widget);
                }
            });
            if (i == 0)
                menu.setDefaultItem(mi);
        }
        item.addListener(SWT.MenuDetect, new Listener() {
            public void handleEvent(Event event) {
                menu.setVisible(true);
            }
        });
        item.setImage(image);
    }
    shell.setBounds(50, 50, 300, 200);
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch())
            display.sleep();
    }
    image.dispose();
    display.dispose();
}

With Adobe AIR and BlazeDS or LCDS you can easily build this type of application.

使用Adobe AIR和BlazeDS或LCDS,您可以轻松构建此类应用程序。

I would go for FreePascal. It compiles natively to windows / mac / linux and because of this you do not depend on any other framework (.net, java, air) to be installed. Just one single executable and that's it.

我会去FreePascal。它本身编译为windows / mac / linux,因此你不依赖于任何其他框架(.net,java,air)来安装。只有一个可执行文件,就是这样。

I agree with James: if you have an investment and know-how in Flex, it makes sense to extend that with Air.

我同意James的观点:如果你在Flex中有投资和技术诀窍,那么将它扩展到Air是有意义的。

As for the payload - if you simply need to 'pop up' notifications from time to time, RSS is the way to go. Otherwise, roll you own XML REST-like service, since it's easy to set up and will give you flexibility in the long run.

至于有效载荷 - 如果您只是需要不时“弹出”通知,RSS就是要走的路。否则,请使用类似XML REST的服务,因为它易于设置,从长远来看,它将为您提供灵活性。
