    ok...I guess I can bite the nail here then...below is a function that will do what u want exactly. When this method is called it will show the file chooser dialigue and will return a handle to the file that a user may selects..

    PHP Code:
        /**
         * creates a file selection dialogue. And then returns the selected file for users work.
         *
         * @return File
         */
        
    public static File getFile() {
            
    File file;
            
    file null;

            
    JFileChooser fileChooserDialogue = new JFileChooser();
            
    fileChooserDialogue.setFileSelectionMode(JFileChooser.FILES_ONLY);
            
    int result fileChooserDialogue.showOpenDialog(parent);
            if (
    result == 0) {
                
    file fileChooserDialogue.getSelectedFile();
                if (
    file == null) {
                    
    JOptionPane.showMessageDialog(null"Invalid file name""Invalid file name"JOptionPane.ERROR_MESSAGE);
                }
            }
            return 
    file;
        } 
    if you are not using static methods then remove the static keyword from the method name decalration....
    Cheers

    Khalid
