  JFileChooser fc=new JFileChooser()
    public void approveSelection()
      File f = getSelectedFile();
      if (f.exists() && f.isFile() && f.getName().endsWith(".dat"))
        JOptionPane.showMessageDialog(null, "Wrong file","File not Writable",JOptionPane.ERROR_MESSAGE);
        return;
      fc.approveSelection(); //Infinite loop caused here.  Try using super.approveSelection();
  };
