java - How to save data from JEditorPane?

Question

So first of all I want to use my JEditorPane as a "note field" and I want it to save the text, so I still can see it the next time I either reload the data or when I next open the window (frame).

I tried this code, but it wont function and I don't get any errors? And at the same time the buttons texts "save" and "load" disappears from my frame (visually) when I run it?

Code:

//imports

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import numerologi.common.RessourceManager;
import numerologi.common.SaveData;

    private JPanel contentPane;
    private JMenuBar menuBar;
    private JMenu ForsideMenu;
    private JMenuItem menuopret, menuKliste, menuNF, menuNliste;
    private JLabel LabelNoter;
    private JButton BButton,BSave,BLoad;
    private JEditorPane editorPane;
    
// classes/sites
    private static Klient Klientside = new Klient();
    
    
    
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Noter frame = new Noter();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace(); }
}
});
}

public Noter() {
    
    initComponents();
    createEvents();

SaveData Class:

}

RessourceManager Class:

import java.io.*;
import java.nio.file.Files;
import java.nio.file.Paths;


public class RessourceManager {

    public static void save (Serializable data, String fileName) throws Exception {
        try (ObjectOutputStream oos = new ObjectOutputStream (Files.newOutputStream(Paths.get(fileName)))) {
                oos.writeObject(data); }
    }
    public static Object load(String fileName) throws Exception {
        try (ObjectInputStream ois = new ObjectInputStream (Files.newInputStream(Paths.get(fileName)))) {
            return ois.readObject(); }
    }
