Save button within JFrame not working

11 views

Hi all,

Firstly, apologies if I have posted this in the wrong section however i think my problem is more relevant to Swing rather than XML.

I have a programme that when a button is selected on the main JFrame, an XML file is loaded into memory and a document / object created; this works fine.

I then pass this XML document / object as a parameter to a constructor onto another JFrame to be used within this second JFrame; again this works fine.

However, my problem lies when i try and save this object by using a save button i have created on the second JFrame; when i press the save button, i get a blank XML document i.e. the initial document hasnt saved.

Here is the code for the first button on the first JFrame which loads the XML file and creates an object:

private void LoadFilePressed (java.awt.event.MouseEvent evt) {                                      
              
            //==========================================
            //   Load the .xml template into memory                
            //==========================================

File fXmlFile = new File("c:\\XML.xml");
              DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
              DocumentBuilder dBuilder = null;
        
        try {
               dBuilder = dbFactory.newDocumentBuilder();
              } catch (ParserConfigurationException ex) {
               Logger.getLogger(BatchCreatorForm.class.getName()).log(Level.SEVERE, null, ex);
             }
              dbFactory.setNamespaceAware(true);
              Document doc = null;
        try {
            doc = dBuilder.parse(fXmlFile);
        } catch (SAXException ex) {
            Logger.getLogger(BatchCreatorForm.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
            Logger.getLogger(BatchCreatorForm.class.getName()).log(Level.SEVERE, null, ex);
        }

CMSPage1 nf = new CMSPage1(doc); 
  
    new CMSPage1().setVisible(true); 
    setVisible(false);
 
    }
