Question

I am using Swing Application Framework JSR(296) for my Swing based Java application.

Similar to AboutBox, I have followed the usage of @Action and added some JDialog classes to my project.

The problem is, when I close the main frame, my application still runs in background.
To overcome this I added following code to the configureWindow() of my main application class:

protected void configureWindow(java.awt.Window root) {

    root.addWindowListener(new WindowAdapter() {
        @Override
        public void windowClosing(WindowEvent e) {
        // write your code here
            Application.getInstance(MyApp.class).exit();
        }
    });
}

But with this modification whenever I close the the dialog (including AboutBox), it also closes the main frame.

What should I do to prevent the entire application from exiting and just close the dialog box?

Update:
I am using NetBeans IDE 7.01 which allows to create Swing Application Framework project.
It generates a project skeleton as shown below:

MyApp 
|--myapp 
|   |--MyApp.java
|   |--MyAppAboutBox.java
|   |--MyAppView.java
|
|--myapp.resources
    |--MyApp.properties
    |--MyAppAboutBox.properties
    |--MyAppView.properties

NetBeans IDE allows to add actions from Window->Properties menu.

MyApp class extends org.jdesktop.application.SingleFrameApplication which is my main class.

MyAppView extends FrameView which is my main view.

Implementation classes of javax.swing.JDialog are in the myapp.view package.

The WindowEvent class has a method call getWindow(), which returns the window that is closing.

Inside your windowClosing method you can check: if the window is the main application window, use the code that you currently have. If it is not, just call Window.dispose()

Edit: I didn’t notice that you were creating custom dialogs in your application. Maybe you forget to dispose them? You should add code like the one in the auto generated about box:

@Action public void closeAboutBox() {
    dispose();
}

and call this action whenever the dialog closes. If this is not the problem, a thread dump will probably help you in order to find out which thread is running when you close the main window.
