Serialization to String (easy code to try!) PLEASE HELP!!!!!!!!!!!

Question

My last post is a bit ard to understand, I submit this easy code which cause the same trouble!
If anybody has some explanation I realy would be very grateful!!!!
Code : -----------------------------------------------------------------------------------------------
import java.io.*;
import java.util.*;
public class prova {
  public static void main(String[] args) {
// builds a simple ArrayList object -----------------------------------------------------
    ArrayList l=new ArrayList();
    ArrayList l1=new ArrayList();
    l1.add(new String("1-1"));
    l1.add(new String("1-2"));
    l1.add(new String("1-3"));
    ArrayList l2=new ArrayList();
    l1.add(new String("2-1"));
    l1.add(new String("2-2"));
    l.add(l1);
    l.add(l2);
try{
      // Serializes the ArrayList to a String -----------------------------------------------------
     ByteArrayOutputStream ByteOutStream=new ByteArrayOutputStream();
    ObjectOutputStream ObjBuff=new ObjectOutputStream(ByteOutStream);
    ObjBuff.writeUnshared(l);
    ObjBuff.flush();
    ObjBuff.close();
    String SerializedCommand=new String(ByteOutStream.toByteArray());
    // Deserializes it -----------------------------------------------------
    ByteArrayInputStream ByteInStream=new ByteArrayInputStream(SerializedCommand.getBytes());
    ObjectInputStream ois=new ObjectInputStream(ByteInStream);
    ArrayList result=(ArrayList)ois.readUnshared();
    System.out.println(result);
  catch (Exception e){e.printStackTrace();}
}

hi, try it with xmlencoder and decoder!
// Serialize
ByteArrayOutputStream ByteOutStream=new ByteArrayOutputStream();
XMLEncoder ObjBuff=new XMLEncoder(ByteOutStream);
ObjBuff.writeObject(l);
ObjBuff.close();
String SerializedCommand=new String(ByteOutStream.toByteArray());
// Deserializes it
ByteArrayInputStream ByteInStream=new ByteArrayInputStream(SerializedCommand.getBytes());
XMLDecoder ois=new XMLDecoder(ByteInStream);
ArrayList result=(ArrayList)ois.readObject();
System.out.println(result);it should work.
greetings,
