Java SE (Java Platform, Standard Edition)

I'm trying to use a JFileChooser in LINUX to open up a file I will be reading in but the FileChooser does not show any directories or files for me to chose from. It's just and empty FileChooser Window. It has a couple options by the "Look In:" combobox, but again there is nothing to chose from in the window where the folders and files should show up.

The code i have is simple

JFileChooser fc;

...
...

if ("open".equals(e.getActionCommand()))
{
    if (fc == null)
    {
      fc = new JFileChooser();

      fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
    }
}

int returnVal = fc.showOpenDialog(ScenExectureWindow.this);

Again the FileChooser window appears but I don't understand why it is not recognizing ANY files or folders...

Any ideas?
