Filechooser - how to force selection

Question

Hi,
I have an application that needs to load data from two files. I could simply programmatically put the whole file path in the code and the problem is solved. However, it can happen that the user moves those files to a different directory and the system would not find them. So I am using a filechooser.
In reality, I don't want the user to choose anything (!)..just browse through his directories until he finds the relevant files. I want to make sure that the user only has the option to open file "file1.doc" and "file2.doc", with no possibility for his to do anything else.
I have looked at filefilter to put a ".doc" extenstion. Still the user can select "all files". So, that's not good enough. Besides, I haven't managed to pre-select the whole file name. Can someone help me with that?
Is there a way to 'lock' file name in the preselection, or at least, if the user is really stubborn and opens something else, then the filechooser does not accept that choise and re-present the openfile window
thanks

I was feeling bored and this is something that may one day be useful to me ;-) also something I'd implemented in VFP years ago for a similar reason -- to locate the database file on the network (no dedicated server).   File getNamedFile (final String name, final String description) {
      FileFilter filter = new FileFilter () {
         public boolean accept (File f) {
            return (f.isDirectory ()
                  || f.getName ().toLowerCase ().equals (name.toLowerCase ()));
         public String getDescription () {
            return description;
      JFileChooser chooser = new JFileChooser ();
      chooser.addChoosableFileFilter (filter);
      chooser.setAcceptAllFileFilterUsed (false);
      int confirmed = JOptionPane.NO_OPTION;
      do {
         int chosen = chooser.showOpenDialog (null);
         if (chosen == JFileChooser.APPROVE_OPTION
               && chooser.getSelectedFile () != null
               && chooser.getSelectedFile ().getName ().toLowerCase ().equals (name.toLowerCase ())) {
            return chooser.getSelectedFile ();
         confirmed = JOptionPane.showConfirmDialog (null, "The file " + name + " could not be found.\nWould you like to try again?", "Confirm", JOptionPane.YES_NO_OPTION);
      } while (confirmed == JOptionPane.YES_OPTION);
      return null;
   }db
