监听端口

public Zithread(Socket clientSocket){
    Socket socket = new Socket();
    try{
        socket = clientSocket;
        socket.setSoTimeout(10000);
        InputStreamReader isReader = new InputStreamReader(socket.getInputStream());
        OutputStream outputStream = new DataOutputStream(socket.getOutputStream());
        BufferedReader reader;
        reader = new BufferedReader(isReader);
        
        byte[] b = new byte[3000];
        int x;
        StringBuilder sBuilder = new StringBuilder();
        while((x=is.read(b)) != -1){
            sBuilder.append(new String(b, 0, x, "utf-8"));
        }
        String infos = sBuilder.toString();
        Map<String, Object> returnMap = this.dealWithInfos(infos);
        byte[] dateBytes = null;
        dateBytes = JsonUtil.buildJsonMessage(returnMap, "utf-8");
        outputStream.write(dateBytes);
        outputStream.flush();
        is.flush();
        outputStream.close();
        is.close();
    }catch (IOException e){
    }catch (Exception e){
    }finally{
        try{
            socket.close();
        }catch (IOException e){
        }
    }
}


这是我写的监听端口监听后的处理流程，监听到推送报文后进行处理可以接收到对方推送的报文，但是处理后返回报文对方却接收不到，我也用过dateoutputstream意外的方法写输出流，但是对方都接收不到，请问各位大大这是什么原因，本地没有报错，对方也没有报错，只是报的接收超时，对方可以接受其它系统的返回报文
