How need to take screen shot of the screen using java.awt.Robot from javafx

Question

1) I am displaying a Stage which is having an image and shapes in it and wanted to take the screen shot as and when i move the shape( which moves the stage ).
I am trying to java.awt.Robot, but i am getting headless exception. I used
@Override
public void start(final Stage primaryStage) {
// creating some images and shapes
Platform.runLater(new Runnable() {
@Override
public void run() {
// update();
public void update() {
if (stg.isShowing()) {
ScreenCapture.capture(stg.getX() + 2, stg.getY() + 2, (int) boundsOfCircle.getBoundsInParent().getWidth(), (int) boundsOfCircle.getBoundsInParent().getHeight());
magnifierImageView.setImage(new Image(SCREEN_SHOT_FILE));
public static void capture(final double x, final double y, final int width, final int height) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
System.out.println("x ="+x +" y = "+y +" width "+width +" height ="+height);
Robot robot = new Robot();
} catch (Exception e) {
System.out.println("exception arised while taking the screen shot ");
e.printStackTrace();
The above code throws headless exception.
2) The second issues is have a image & i am dividing the image into different rows and cols( images of same size ). This is i am doing using awt. and i wanted to load those different images into
javafx images . I am facing the issues when i try to load the images into javafx.
