Как сохранить изображение в папке ресурсов java swing

Question

Я пытаюсь сохранить файл изображения в папке ресурса в NetBeans, но у меня проблема с поиском пути к папке ресурса.

Мой код ниже:

JFileChooser fileChooser = new JFileChooser();
    FileNameExtensionFilter filter = new FileNameExtensionFilter("*.Images", "jpg", "gif", "png", "jpeg");
    fileChooser.addChoosableFileFilter(filter);
    int result = fileChooser.showSaveDialog(null);
    if (result == JFileChooser.APPROVE_OPTION) {
        path = fileChooser.getSelectedFile().getAbsolutePath();
        filename = fileChooser.getSelectedFile().getName();
         String fullPath = getClass().getResource("/resource").toString();
                                        System.out.println(fullPath);
        System.out.println(filename);
        System.out.println(path);
        Image img = null;
        try {
            img = ImageIO.read(fileChooser.getSelectedFile());

        } catch (IOException ex) {
            Logger.getLogger(AddItems.class.getName()).log(Level.SEVERE, null, ex);
        }
        ImageIcon image = new ImageIcon(img.getScaledInstance(208, 104, 208),path);

        jlblImage.setIcon(image);

    } else {
        JOptionPane.showMessageDialog(null, "No file selected.");
    }

private void jbtnSubmitActionPerformed(java.awt.event.ActionEvent evt) {                                           
    // TODO add your handling code here:
    String itemname = jtxtItemName.getText();
    String category = jcboCategory.getSelectedItem().toString();
    String description = jtxtAreaDescription.getText();
    String reservedPrice = jtxtReservedPrice.getText();
    String image =filename;

    if (itemname.isEmpty() || category.isEmpty() || description.isEmpty() || reservedPrice.isEmpty() || image.isEmpty()) {
        JOptionPane.showMessageDialog(null, "All fields are required.");
    }  else {
        Item item = new Item(category, description, reservedPrice, itemname, image);
         try {
             int i = itemdao.createItem(item);
             if(i> 0 ){
                 File sourceFile = new File(path);
                 File destinationFile = new File("resources/Image/"+ filename);
                 BufferedReader reader;
