Im trying to work JavaFX with IntelliJ-IDEA. I already set the Scene Builder path, and the requiered JavaFX JARS and libraries but I still get this error that I dont know how to fix.
I havent really tried anything to fix this because all the solutions that I find arent for the same problem
Code:
package sample;
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("sample.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
FXML:
<?import javafx.geometry.Insets?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<GridPane fx:controller="sample.Controller"
xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10"
vgap="10">
</GridPane>

Exception running application sample.Main
I just figured it out. I updated the JDK to the latest available and downloaded the latest JavaFX library. After that I just left the VM options by default with nothing added (Run -> Edit Configurations -> VM Options). After that, everything worked as expected

I create playerMp3. I'm trying to create a GUI in ScenBuilder and import it into my code. I use FXMLoader for this, but I get an error when compiling. In the module-info I have indicated that I use javafx.fxml. I don't know what the error is. I have java 14, JavaFX SceneBuilder 2.0 and the latest InteliJ .

I am getting lots of errors when trying to execute the show() method from JavaFX's Stage class. I am using Intellij IDEA. This is the base code generated by the IDE and I have been experiencing a lot of issues trying to set it up. I have been able to fix the other 10 errors I had to deal with but I cannot figure out how to fix this one.
This is my application class:
package sample;
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("sample.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
and this is the error I am getting:

Exception running application application.Main
Finally the programs runs (I just needed to change VM arguments in runs configuration)
The reason for your error is that you don't have file hellofx.fxml in your sources. That's why you got NPE. Call getClass().getResource("hellofx.fxml") is trying to read not existing file and returns null.
This file contains the structure of UI you want to have in your JavaFX application.
Try to take a look into this tutorial to find out how to make this file https://docs.oracle.com/javafx/2/get_started/fxml_tutorial.htm
I've added two image views in a stackpane layout that I've created but when I try to add a button node inside my StackPane layout, while the images work just fine, the button doesn't allow the program to run and throws this exception which I cannot figure out:

primaryStage.setScene(new Scene(root, 900, 700));
primaryStage.setResizable(false);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);

}
Hopefully someone in here can help me solve this(it's probably something "stupid" but still...I can't seem to find the solution to this exception!
You cannot use dash (-) in the id as it means minus operation. Replace it with underscore(_) or use camelCase.
I am facing problem in loading fxml file from different packge.
Project Structure
My class that loads the FXML file PlayArea.java looks like this:

public class PlayArea extends Application {

Parent root = FXMLLoader.load(getClass().getResource("/gui/FXMLDocument.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
My fxml file that is FXMLDocument.fxml

Exception running application controller.PlayArea
The problem is with your this line
Parent root = FXMLLoader.load(getClass().getResource("/gui/FXMLDocument.fxml"));
just replace it with
Parent root = `FXMLLoader.load(getClass().getResource("../gui/FXMLDocument.fxml"));`
if you still get the error then
create a file outsite of your packages i.e. in src folder say Main.class
now use this
FXMLLoader.load(Main.class.getResource("gui/FXMLDocument.fxml"));
You can set the controller in the fxml file itself if you're right click and open the file you will find properties and there you will have a tag called controller and you can type the exact folder path .
FXML EG
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" fx:controller="javafxapplication.FXMLController">
</AnchorPane>
Updating the previous answer
Here is what tried and it is working fine
Parent root = FXMLLoader.load(getClass().getResource("/fxml/Main.fxml"));
Scene scene = new Scene(root, 300, 275);
stage.setTitle("FXML Welcome");
stage.setScene(scene);
stage.show();
Hope this Solves the Query
I had to change 2 lines to properly open FXML file from controller located in another packet:
root = loader.load(Main.class.getResource("document.fxml").openStream());
scene.getStylesheets().add(Main.class.getResource("application.css").toExternalForm());
Instead of getClass(), there is Main.class .
