How to return the message in MTI and bitmap?

Question

Here we receive xml message from client but the problem is this coding is for the first time it receive MTI message, so how can i do if i receive from client in xml type then convert to MTI then response it as xml again to client.
Is it too hard to understand?????
     * Waits and receive an ISOMsg over the TCP/IP session
     * @return the Message received
     * @exception IOException
     * @exception ISOException
    public ISOMsg receive() throws IOException, ISOException {
        byte[] b=null;
        byte[] header=null;
        LogEvent evt = new LogEvent (this, "receive");
        ISOMsg m = createMsg ();
        Socket socket = getSocket();
        m.setSource (this);
        try {
