JFileChooser for selecting a directory !!

Question

Hi,
here's a question for u. I am using a JFileChooser with an "Open" dialog for
choosing a directory by
JFileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY). Now it
works fine, except when i double click on a directory, which sets the
directory name in the "File Name" text box, now if I press "Open", it does
nothing, coz it cannot find that directory in this directory as it is
already in that directory!!
The way to make it work is to clear the "File Name" box and then press
"Open", which is very unprofessional and no dumb user will think of doing
that.
What feel is that the only way to do this is to be actually able to
access/modify the Open dialog box, which as far as I know, there is no way
as it is handled by the JVM itself.
Thanks for ur consideration.

There are several problems with choosing directories from the JFileChooser, (I won't go into them here). I have written the following class to choose directories. I have only tested this some on windows, but it could be a good starting point for others.
import javax.swing.*;
import java.io.*;
import javax.swing.plaf.*;
import javax.swing.plaf.basic.*;
public class DirectoryChooser extends JFileChooser {
    public DirectoryChooser(File startDir) {
        super(startDir);
        this.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    public File getSelectedFile() {
        File    file    = super.getSelectedFile();
        if (file == null) {
            return file;
        String  dirName = super.getSelectedFile().getAbsolutePath();
        String  fileSep = System.getProperty("file.separator", "\\");
        if (dirName.endsWith(fileSep + ".")) {
            dirName = dirName.substring(0, dirName.length() - 2);
            file    = new File(dirName);
        return file;
    public void setCurrentDirectory(File file) {
        // Let the action take place, then override the 'Name' field.
        // This is equivalent to the user typing "." in the name field.
        super.setCurrentDirectory(file);
        FileChooserUI ui = getUI();
        if (ui instanceof BasicFileChooserUI) {
            ((BasicFileChooserUI)ui).setFileName(".");
