Answer 1

Set a FileView and override the isTraversable method so that it returns true only for the directory you want the user to see.

Here is an example:

String getProperty = System.getProperty("user.home");
final File dirToLock = new File(getProperty + "/Dropbox/Prosjekt RMI/SERVER/");
JFileChooser fc = new JFileChooser(dirToLock);
fc.setFileView(new FileView() {
    @Override
    public Boolean isTraversable(File f) {
         return dirToLock.equals(f);
    }
});
