    try {//from  ww  w . j a v a  2  s.c  om
        // File to serialize object to
        String fileName = "testSerialization.ser";

        FileOutputStream fos = new FileOutputStream(fileName);

        // Serialize String
        SerializationUtils.serialize("SERIALIZE THIS", fos);
        fos.close();

        // Open FileInputStream to the file
        FileInputStream fis = new FileInputStream(fileName);
