JavaFX的Netbeans的错误：没有合适的方法发现

Question

我使用NetBeans 7.2，当我想这个tutorial我得到这个错误：

类代码如下：

public class Login extends Application { 

@Override 
public void start(Stage primaryStage) { 
    GridPane grid = new GridPane(); 
    grid.setAlignment(Pos.CENTER); 
    grid.setHgap(10); 
    grid.setVgap(10); 
    grid.setPadding(new Insets(25, 25, 25, 25)); 

    Text sceneTitle = new Text("Welcome"); 
    sceneTitle.setFont(Font.font("Tahoma", FontWeight.NORMAL, 20)); 
    grid.add(sceneTitle, 0, 0, 2, 1); 

    Label userName = new Label("User Name:"); 
    grid.add(userName, 0, 1); 

    Label pw = new Label("Password:"); 
    grid.add(pw, 0, 2); 


    Scene scene = new Scene(grid, 300, 275); 
    primaryStage.setScene(scene); 

    primaryStage.setTitle("JavaFX Welcome"); 
    primaryStage.show(); 
} 

/** 
* The main() method is ignored in correctly deployed JavaFX application. 
* main() serves only as fallback in case the application can not be 
* launched through deployment artifacts, e.g., in IDEs with limited FX 
* support. NetBeans ignores main(). 
* 
* @param args the command line arguments 
*/ 
public static void main(String[] args) { 
    launch(args); 
} 
} 

我使用JavaFX 2

这方面有任何想法？
