Javafx Exception in program Start Method - javafx

Question

I am facing error while running my JavaFX code. I created this simple stage and it says exception in program start method and much more. I am using Scene Builder 11 with IntelliJ IDEA 11.0.7. Any help will be appreciated.
package calculate;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("view.fxml"));
primaryStage.setTitle("cal");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
This is the error I am facing. I tried everything that I know but I am not able to solve the issue.

What can be done to resolve the issue?

Answer 1

I think you haven't added javafx.fxml to your VM Arguments. Use this:
--module-path "\path\to\javafx-sdk-14\lib" --add-modules javafx.controls,javafx.fxml
You could also add javafx.media if you plan on using it in the future.
