Here is my class where I've written the one liner code to link the fxml file to the project I'm working on:
package application;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
public class towerOfHanoi extends Application implements Initializable
{
public static void main(String[] args)
{
launch(args);
}
public void start(Stage primaryStage) throws Exception
{
try
{
Parent rootContainer = FXMLLoader.load(getClass().getResource("/application/userInterface.fxml"));
Scene s=new Scene(rootContainer);
primaryStage.setScene(s);
//primaryStage.setTitle("Towers Of Hanoi");
primaryStage.show();
}
catch(IOException e)
{
// e.printStackTrace();
}
}
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
// TODO Auto-generated method stub
}
}
Any time I try to run this in eclipse, nothing happens. The square to terminate is red as if something is happening, but the UI I created in scenebuilder doesn't show.
****Update:
This is the complete stack trace when I uncomment that piece of code:

As the error tells you : you need to associate a controller to the .fxml, like this :
FILE userInterface.fxml (you can have another container than a BorderPane but it will be the same, it has to be on the root parent)
<BorderPane fx:id="background" fx:controller="application.Controller">
//Content ...
</BorderPane>
you can set the Controller into the fxml (see above) OR by SceneBuilder:
Also It will be clearer to separate the Launcher and the controller, like this :
FILE towerOfHanoi.java
public class towerOfHanoi extends Application{
public static void main(String[] args){
launch(args);
}
public void start(Stage primaryStage) throws Exception{
try{
Parent rootContainer = FXMLLoader.load(getClass().getResource("/application/userInterface.fxml"));
Scene s=new Scene(rootContainer);
primaryStage.setScene(s);
//primaryStage.setTitle("Towers Of Hanoi");
primaryStage.show();
}
catch(IOException e){
// e.printStackTrace();
}
}
}
FILE Controller.java
public class Controller implements Initializable {
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
// TODO Auto-generated method stub
}
}

I'm trying to execute a .jar file which I produced from a JavaFX project (i already set the VM Options in Intellij with module path and modules to include) but I keep getting this error

I also have a Launcher class, which Main method just does Main.main(args), where Main is the class that extends Application.
What can i do more?
This is the main class of my project
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
try {
Parent root = FXMLLoader.load(getClass().getResource("/fxml/InserimentoPorta.fxml"));
primaryStage.setTitle("EP Miner");
primaryStage.setScene(new Scene(root));
primaryStage.show();
}catch (IOException e){
System.out.println(e.getMessage());
System.exit(-1);
}
}
public static void main(String[] args) {
launch(args);
}
}
And there are 3 controllers, one for each of my fxml file (i'm not posting the controllers code because the question would be too long and i don't think it's necessary to solve this problem)
The file "icon.png" is in the same folder as class. But if i just use (new Image("icon.png")) then it says java.lang.IllegalArgumentException: Invalid URL: Invalid URL or resource not found. But now after adding getClass().getResource... i'm getting this error. Here is my code:
package application;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.image.Image;
public class Main extends Application {
public void start(Stage primaryStage) {
try {
Parent root = FXMLLoader.load(getClass().getResource("NewFile.fxml"));
Scene scene = new Scene(root);
primaryStage.setResizable(false);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.getIcons().add(new Image(getClass().getResource("icon.png").toExternalForm()));
primaryStage.show();
}
catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
And here is the error:

Please help me to fix it. Thanks in advance!
NullPointerException error is caused due to location of your image is not in the proper position your refer to something which not exist
you can edit your post to show us your project construction
it should be somthing like that to work !
I tried to build a simple scene by using scene builder. But i failed to make a main.java file to run the code! i can't understand what's the wrong!
Here's my FXMLDocumentController.java file:
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
public class FXMLDocumentController {
#FXML
void btnHandle(ActionEvent event) {
}
}
And here's the fxml file:
sample.fxml
And the Main.java

Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**

public static void main(String[] args) {
launch(args);
}
}

I suggest to cange the root class in the main from Parent to AnchorPane:
public class Main extends Application {
#Override
public void start(Stage stage) throws Exception {
AnchorPane root = FXMLLoader.load(getClass().getResource("sample.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);
}
}
Just as a quick explanation I'm just trying to set up a StackPane that contains two GridPanes, one right on top of each other. As you may be able to tell from the class names I'm trying to make a strategy game and I'd like to have a GridPane that acts as the background environment and then a GridPane on top of that that stores player units and that will capture all click events.
I've gotten the StackPane to load no problem but then I try to load both the environment GridPane and the unit GridPane inside the StackPane's initialize function and I keep getting a LoadException from that. I tried a few different things with the paths but that didn't change anything.
Here's where I'm currently at:
Main.java
package application;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
try {
StackPane root = FXMLLoader.load(getClass().getResource("/application/battleGrid/BattleGrid.fxml"));
primaryStage.setScene(new Scene(root, 700, 700));
primaryStage.show();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
BattleGridController.java
package application.battleGrid;

import javafx.fxml.FXMLLoader;

public class BattleGridController {
#FXML
private StackPane stack;
public void initialize() {
try {
GridPane environmentGrid = FXMLLoader.load(Main.class.getResource("/application/environmentGrid/EnvironmentGrid.fxml"));
GridPane unitGrid = FXMLLoader.load(Main.class.getResource("/application/unitGrid/UnitGrid.fxml"));
stack.getChildren().addAll(environmentGrid, unitGrid);
} catch (LoadException e) {
e.printStackTrace();
System.out.println(e.getMessage());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
BattleGrid.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.StackPane?>
<StackPane xmlns:fx="http://javafx.com/fxml/1"

<GridPane xmlns:fx="http://javafx.com/fxml/1"

There's currently nothing in the controllers for the environment and unit grid so there should be no issues there.
Here's the stack trace:

Edit:

to
FXMLLoader.load(Main.class.getResource("/application/unitGrid/UnitGrid.fxml"));
Same issue still occuring
Your code is loading this:
Main.class.getResource("/application/unitGrid/unitGrid.fxml")
However you are stating it's name has an UPPER case "U"
UnitGrid.fxml
Try changing to case sensitive loading.
The stack trace is indicating that the Location is not set. It means that the resource path is not found by the FXMLLoader. As suggested by the purring pigeon make those changes.
UPDATE
To load the resource use the CurrentThread,
Thread.currentThread().getContextClassLoader().getResource("fxml_file_path")
I am trying to create a very simple VBox with a black background. Thats all. Nothing else. I am using FXML to describe my VBox.

Why is this happening? Please let me know if I am making any mistake or if I am missing out anything.
Is nothing to do with Intellij, I also had this issue.
I was compiling with Java 1.8, I changed to 1.7 and works.
