I just wrote this code here:
package SpellcheckerClient;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
BorderPane root = FXMLLoader.load(getClass().getResource("/controller/gui.fxml"));
Scene scene = new Scene(root);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.setTitle("Spellchecker Client");
primaryStage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
And this is the corresponding controller.
package controller;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
import spellchecker.remote.SpellcheckerRemoteAdapter;
public class Controller {
@FXML
TextField input;
@FXML
Button send;
@FXML
TextArea area;
@FXML
Button connect;
private SpellcheckerRemoteAdapter adapter;
@FXML
private void send() throws RemoteException{
String toCheck = input.getText();
this.area.appendText(toCheck + "\n");
this.area.appendText(checkRoutine(toCheck, this.adapter) + "\n\n");
this.input.clear();
}
public void initiateConnection() {
try {
Registry registry = LocateRegistry.getRegistry(1088);
this.adapter = (SpellcheckerRemoteAdapter) registry.lookup(SpellcheckerRemoteAdapter.NAME);
this.area.appendText("Verbindung erfolgreich aufgebaut!\n");
connect.setDisable(true);
} catch (Exception e) {
if(this.adapter == null) {
this.area.appendText("Server nicht gefunden!\n");
}
}
}
private static String checkRoutine(String input, SpellcheckerRemoteAdapter adapter) throws RemoteException {
if (input == null || input.isEmpty()) {
return "Bitte etwas eingeben!";
}
String[] words = input.split(" ");
boolean control = true;
String output = "";
for(String word : words) {
if(!adapter.check(word)) {
control = false;
output += word + ":\t" + adapter.getProposal(word) + "\n";
}
}
if(control) {
return "Alles Okay!\n";
}
return output;
}
}
If I run this code on my Laptop, where I wrote it, it runs perfectly fine in Eclipse and as runnable Jar. However, if I try to run the JAR on another computer i receive this error message:

On my Laptop and my Computer are the same Versions of the JDK/JRE installed. I don't really get what the error message is telling me.

I found that this error may cause java sub versions. For example, I need java 1.8.0_221 version but the system 1.8.0_341. Therefore, I got same exception and changed the environment settings.

Hello I have the same issue on my Eclipse environnement (Windows 10 OS), adding in VM option -Djava.library.path="C:\WINDOWS\Sun\Java\bin" solved my problem
That means that javafx-graphics-[version]-win.jar call some native dll. And You have to found were those dll is stored. I found the path, thanks to jvisualvm and showing the VM option for the case where it's the application run correctly.
Hoping that it will solve your problem.

Which JDk you have installed?? I have the same issue and i use JDK 8 instead of JDK 9. Which helped me.Sample Image of Exception
This is because jar which i created it was created on JDK 8 through a different system. Where as when it was executing on another system which has JDK9. So it is version incompatible.
After keeping single JDK 8 and mapped it to system environment when i try to run my jar it worked for me.
Good Luck :)
