我正在使用 Netbeans 7.2，当我尝试本教程时，我收到了这个错误：
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

* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
我正在使用 JavaFX 2
有什么想法吗？
