    Problem on Compiling the JavaFX/FXML project with the default code

      I just installed NetBeans 7.1.2, and JDK 7U4 and JavaFX2.1 Runtime, JavaFX2.1 SDK., then I used NetBeans to create a new JavaFx project with the default code, ans it ran fine to give "Hello World" on the console. Good... Then I used NetBeans to create a new JavaFX/FXML project with the default code -- Sample.java, Sample.fxml, and the main program, but then I got problem when I ran it. Please can someone tell me what gent wrong with my case. The following is the output on the console :
      Created dir: C:\FXML Code\MyFXML002\build
      Updating property file: C:\FXML Code\MyFXML002\build\built-jar.properties
      Created dir: C:\FXML Code\MyFXML002\build\classes

      The following are the copies of the code generated by NetBeans, none of them is my code.

      1. MyFXML002.java---

      package myfxml002;

      import javafx.application.Application;
      import javafx.fxml.FXMLLoader;
      import javafx.scene.Parent;
      import javafx.scene.Scene;
      import javafx.stage.Stage;

      * @author Administrator
      public class MyFXML002 extends Application {

      public static void main(String[] args) {
      Application.launch(MyFXML002.class, args);

      public void start(Stage stage) throws Exception {
      Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));
      stage.setScene(new Scene(root));

      2. Sample.java---

      package myfxml002;

      import java.net.URL;
      import java.util.ResourceBundle;
      import javafx.event.ActionEvent;
      import javafx.fxml.FXML;
      import javafx.fxml.Initializable;
      import javafx.scene.control.Label;

      * @author Administrator
      public class Sample implements Initializable {

      private Label label;

      private void handleButtonAction(ActionEvent event) {
      System.out.println("You clicked me!");
      label.setText("Hello World!");

      public void initialize(URL url, ResourceBundle rb) {
      // TODO

      3. Sample.fxml---

      <?xml version="1.0" encoding="UTF-8"?>

      <?import java.lang.*?>
      <?import javafx.scene.*?>
      <?import javafx.scene.control.*?>
      <?import javafx.scene.layout.*?>

      <AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml" fx:controller="myfxml002.Sample">
      <Button id="button" layoutX="126" layoutY="90" text="Click Me!" onAction="#handleButtonAction" fx:id="button" />
      <Label id="label" layoutX="126" layoutY="120" minHeight="16" minWidth="69" prefHeight="16" prefWidth="69" fx:id="label" />
