    oos.writeObject(v);// w  w  w  . ja v a  2  s  .co m
    oos.close();
    ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
    ObjectInputStream ois = new ObjectInputStream(bais);
    Vector v2 = (Vector) ois.readObject();
    Enumeration e = v.elements();
    while (e.hasMoreElements()) {
        System.out.println(e.nextElement());
