Try the following, this worked for me:

Image image = new Image(XYZ.class.getClassLoader().getResource("my.png").toExternalForm());
stage.getIcons().add(image);

If you're using Linux, you may be interested in this question.

Here is a MWE:

public class Main extends Application {

    @Override
    public void start(Stage stage) throws Exception {
        stage.getIcons().add(new Image(Main.class.getClassLoader().getResource("sample/icon.png").toExternalForm()));
        stage.setScene(new Scene(new Group(), 300, 275));
        stage.show();
    }

    public static void main(String[] args) {launch(args);}
}

This assumes that there is an image icon.png in directory sample (which is the same directory as the Main class). As you can see, the icon is both in the task bar and in the title bar of the application:

Thank you for replay but this is not working and giving java.lang.NullPointerException – Gaali Prabhakar May 19 '15 at 13:34
The NPE is most likely caused by a wrong path to the image. Make sure to set the full path like the last example in your post. – Aerus May 19 '15 at 13:39
my image is visible in task bar of my app but not showing at title bar – Gaali Prabhakar May 19 '15 at 13:44
Do you mean the MWE is not working for you? This is the result on my end: http://i.stack.imgur.com/yuK5O.png – Aerus May 19 '15 at 13:50
i found the problem i using Linux in linux that is not working in windows its working beautifully Thx so much – Gaali Prabhakar May 19 '15 at 13:59
In that case, it may be because of the dimensions of the icon, take a look at the link i edited in, maybe it helps you :) – Aerus May 19 '15 at 14:07
