StreamCorruptedException invalid type code: 01

Question

ok here's the deal. this is another one of those "help me, objectinput/outputstream sucks" anyways, i'm making a program which will play a board game between two computers over a ServerSocket network and I'm using a dataTransfer class to hold any chat messages (there's a chat box incorporated in the UI), and the matrices of the different players' pieces. It was working fine until I added in the matrices. It also works fine when I run two instances of the program on the localhost, but when it's on two seperate computers I get a StreamCorruptedException error on the receiving end at this line:
input=(dataTransfer)in.readObject();
here's what my dataTransfer class looks like:
public class dataTransfer implements Serializable {
     private String s;
     private boolean chat;
     private int[][]hostPieces;
     private int[][]clientPieces;
     public dataTransfer(String s1, int[][]p1,int[][]p2, boolean c)
          chat=c;
          s=s1;
          hostPieces=p1;
          clientPieces=p2;
     public dataTransfer(int[][]p1,int[][]p2)
          chat=false;
          hostPieces=p1;
          clientPieces=p2;
     public String getString(){return s;}
     public boolean isChat(){return chat;}
     public int[][] getHostPieces()
          return hostPieces;
     public int[][] getClientPieces()
          return clientPieces;
}I'm guessing that there's something about matrices that will not allow me to send them over the ObjectOutputStream and/or receive them on the ObjectInputStream. Any tips, suggestions, comments?

ok, here's my connection method, which is only called once and which sets up my socket and in and out streams
public void connect()
    if(isHost){
        while(!connected){
    try{
    srvr=new ServerSocket(1234);
    skt=srvr.accept();
    if(skt.isConnected())connected=true;}catch(Exception e){}}}
    else{
        while(!connected){
            try{
                skt=new Socket(hostIP,1234);
                if(skt.isConnected())connected=true;
            }catch(Exception e){e.printStackTrace();}
    xtext.append("Computer: Connected"+"\n");
    if(skt.isConnected()){
    try{
     out=new ObjectOutputStream(skt.getOutputStream());
    in=new ObjectInputStream(skt.getInputStream());
    }catch(Exception e){e.printStackTrace();}}
}and here's my method which sends the text. while the actual dataTransfer class contains matrices, i've only gotten to the point of sending the text messages but even that's not working
public void SendText(String s)
data=new dataTransfer(s+"\n",myPieces,myPieces,true);
    try{
    out.writeObject(data);
    out.flush();
    out.reset();}catch(Exception e){e.printStackTrace();}
}and here is the code that's giving me so much trouble
while(!inGame)
         if(connected){
         try{
                input=(dataTransfer)in.readObject();
                System.out.println("hello");
                }catch(Exception e){e.printStackTrace();}
                if(input!=null)xtext.append("Opponent: "+input.getString());}
            repaint();
        }hope that's decently clear. any help is much appreciated
