JFileChooser doesn't show any file!!

Question

Hi all,
I am developing an java application that uses JFileChooser to choose a directory. However, very strange, the JFileChooser opened does not show any file or directory in C: drive nor D: drive. How can that happen? Anyone knows?
JFileChooser fileChooser = new JFileChooser();
fileChooser.showOpenDialog(this);Above is my code. When I only execute above code, it is normal (can see those files in C: drive). But if i run above code with my application, it doesnot show any file in C: drive. Please help me!!

Try specifying the default location in addition to the component.
if(windows machine) result=createDialog("Choose Parent Directory","Select Folder","C:\\");
private static JFileChooser createDialog(String title,String ilabel,String directory) {
          JFileChooser result= null;
          // TODO Auto-generated method stub
        // Create a window and some components
        JPanel topPanel = new JPanel();
          JLabel label = new JLabel(ilabel);
        JFileChooser jFC = new JFileChooser(directory);
        // Set the window's layout
        label.setAlignmentX(Component.CENTER_ALIGNMENT);
        //set file dialog to use direcotries
        jFC.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        // Setup the text, list, and checkbox
        topPanel.add(label);
        topPanel.add(jFC);
        int returnVal = jFC.showOpenDialog(topPanel);
        if(returnVal == JFileChooser.APPROVE_OPTION) {
            result = jFC;
        } else {
             result=null;
        return result;
     }
