How to specify a controller in a GUI app?

Im doing a simple GUI project with java. Sometimes it notices my fxml file and can run normally, but after a while it chooses to ignore it, throwing the following message:

Exception running application main.Main
My main looks like this(and the allatok.fxml file is located in the main package, next to the main.java):
package main;
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 {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
Parent load = FXMLLoader.load(getClass().getResource("allatok.fxml"));
Scene value = new Scene(load);
primaryStage.setScene(value);
primaryStage.setResizable(true);
primaryStage.setTitle("Kisallat Nyilvantarto Rendszer");
primaryStage.show();
}
}
Where should I put the fxml file, and how should I rename the path?

At your top most XML tag you can specify the Fully Qualified Class Name (FQCN) using the XML attribute fx:controller
Example: AnchorPane
<AnchorPane prefHeight="400.0" prefWidth="600.0"
xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1"
fx:controller="com.zigma.Controller">
The code for com.zigma.Controller
package com.zigma;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.Initializable;
public class Controller implements Initializable{
#Override
public void initialize(URL url, ResourceBundle resourceBundle)
{
System.out.println("controller init");
}
}

UnsatisfiedLinkError occurs on openjfx webkit（32bit）

In order to use webview with amazoncorretto 8 (32bit), I want to build 32bit openjfx.
I could create a library, but when I use it I get an UnsatisfiedLinkError.
Build it with reference to the following URL.

Launching fmxl GUI using javafx on Eclipse, Error in start method

I am trying to launch a fmxl file using eclipse.
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.application.Application;
import java.io.IOException;
import java.util.logging.Logger;
import java.util.logging.Level;

Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
System.exit(1);
}
}
public static void main(String[] args) {

}
However, I keep getting this error.

Exception running application MainProgram
The code appears to run up until this line:
AnchorPane page = (AnchorPane)fmxlLoader.load(
this.getClass().getResource(viewerFxml).openStream());
Really not sure why I'm getting this error.
Any help would be very much appreciated.

It is because the path of file which has to be loaded is not correct.
Try putting the correct file path in your String variable.
that is
String viewerFxml= "~path/Interface.fxml";

Localization code throwing unexpected exceptions in java

I'm working on a project for school. Part of the prompt for the application specifies that I'm supposed to add localization to the log in page to translate the text in to two other languages. I don't have any experience with localization and Internationalization so I looked up a tutorial on YouTube that you can find here.
The tutorial is slightly simpler than what I'm trying to do, but I thought that I extrapolated the information effectively. What I'm about to post is just a test to see if I could get the log-in prompt text to change language, based on a radio button selection by the user. Here is my log in controller class:
import java.net.URL;
import java.util.Locale;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.RadioButton;
import javafx.scene.control.TextField;
import javafx.stage.Stage;
public class LogInController implements Initializable {
#FXML
private Label logInPrompt;
#FXML
private TextField userNameField;
#FXML
private TextField passwordTextField;
#FXML
private RadioButton english;
#FXML
private RadioButton spanish;
#FXML
private RadioButton french;
#FXML
public void Login(ActionEvent event) throws Exception {
if (userNameField.getText().equals("user") && passwordTextField.getText().equals("password")) {
logInPrompt.setText("Log in successful!");
Stage primaryStage = new Stage();
Parent root = FXMLLoader.load(getClass().getResource("MainMenu.fxml"));
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
} else {
logInPrompt.setText("Log in Failed");
}
}
public String enLang = "en";
public String spLang = "sp";
public String frLang = "fr";
public String unitedStates = "US";
public String mexico = "MX";
public String france = "FR";
Locale us = new Locale(enLang, unitedStates);
ResourceBundle rbEn = ResourceBundle.getBundle("C195/MessageBundle_en_US", us);
Locale mx = new Locale(spLang, mexico);
ResourceBundle rbSp = ResourceBundle.getBundle("C195/MessageBundle_es_MX", mx);
Locale fr = new Locale(frLang, france);
ResourceBundle rbFr = ResourceBundle.getBundle("C195/MessageBundle_fr_FR", fr);
public String enLogIn = rbEn.getString("logInPromptEN");
public String spLogIn = rbSp.getString("logInPromptSP");
public String frLogIn = rbFr.getString("logInPromptFR");
public void langSelect(){
if (english.isSelected()){
logInPrompt.setText(enLogIn);
}else if (spanish.isSelected()){
logInPrompt.setText(spLogIn);
}else if (french.isSelected()){
logInPrompt.setText(frLogIn);
}
}
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
Here is an example of one of my properties files, the other two are the same except they are for the other two languages:
logInPromptSP = Ingrese su nombre de usuario y contraseña:
The application runs if I comment out the localization code, but if I run it without the comment I get a list of exceptions and errors a mile long, very few of which I'm familiar with.
To try to figure this problem out, I went back and read through the Localization and Internationalization portion in my OCP study guide, and I searched through StackOverflow using search terms similar to the title of my question.
Any help anyone could offer me on this issue would be greatly appreciated. Also just a quick note: This is the first question I've ever posted on StackOverflow and I read the guidelines but I'm a complete noob at both programming and at using StackOverflow. So please kindly let me know if the way that I formatted my question or the problem I asked about is in any way inappropriate.

JavaFX MediaPlayer throws java.lang.reflect.InvocationTargetException

I've been trying to experiment with the JavaFX MediaPlayer class, and found the following example code in a different thread:
import java.net.URI;
import java.net.URISyntaxException;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;
public class test extends Application {
#Override
public void start(Stage primaryStage)
{
//Add a scene
Group root = new Group();
Scene scene = new Scene(root, 500, 200);
URI file = null;
try {
file = new URI("/home/thomas/voodoo.mp3");
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("POOR URI SYNTAX");
}
Media pick = new Media(file.toString());
MediaPlayer player = new MediaPlayer(pick);
player.play();
//Add a mediaView, to display the media. Its necessary !
//This mediaView is added to a Pane
MediaView mediaView = new MediaView(player);
((Group)scene.getRoot()).getChildren().add(mediaView);
//show the stage
primaryStage.setTitle("Media Player");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I adjusted the file path to point to a real audio file (/home/thomas/voodoo.mp3) and tried running it, but the console output is the following:

Exception running application test
Is there something wrong with my setup, or with my code?
Thanks for the help!
EDIT:
Changed to Media pick = new Media(new File("/home/thomas/voodoo.mp3").toURI().toString()); as per Nash's suggestion, but it still doesn't work. The console output is a little different now, though.

Exception running application test

The problem is your url /home/thomas/voodoo.mp3 that is not valid, indeed the scheme is missing as described into your error message (uri.getScheme() == null! uri == '/home/thomas/voodoo.mp3'), it should start with file:// as it is a file in your local file system such that it should be file:///home/thomas/voodoo.mp3.
But since it is too error prone to build the URI as you currently do because you must ensure that it is properly URL encoded (spaces should be for example replaced with %20) and you need to provide a valid scheme, you had better to use new File(path).toURI().toString() as proposed by Nash.

Try
Media pick = new Media(new File("/home/thomas/voodoo.mp3").toURI().toString());
