readUTF () возвращает ошибку после writeObject ()

Question

Я настраиваю новую систему сервер-клиент.Здесь от клиента объект будет отправлен на сервер.А после получения объекта сервер отправит клиенту строку.

Здесь сервер успешно читает объект.Но когда клиенты хотят прочитать строку, отправленную сервером, возникает исключение EOFException.

на стороне клиента

public static void main(String args[]) throws IOException, EOFException {
    try (Socket socket = new Socket("localhost", 1254)) {

        OutputStream outputStream = socket.getOutputStream();
        InputStream s1In;
        DataInputStream dis;
        try (ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream)) {
            s1In = socket.getInputStream();
            dis = new DataInputStream(s1In);
            Frame frame = new Frame();
            frame.setData("test");
            objectOutputStream.writeObject(frame);

        String st = "";
        while(dis.available() >0){
            st = dis.readUTF();
        }
        System.out.println(st);
        }
        dis.close();
        s1In.close();
    }
}

на стороне сервера

public static void main(String args[]) throws IOException, ClassNotFoundException {
    ServerSocket s = new ServerSocket(1254);
    Socket socket = s.accept(); 
    OutputStream outputStream = socket.getOutputStream();

    ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);


    //input stream
    InputStream inputStream = socket.getInputStream();
    DataInputStream dataInputStream = new DataInputStream(inputStream);
    ObjectInputStream objectInputStream = new ObjectInputStream(inputStream);

    Frame frame = new Frame();
    frame = (Frame) objectInputStream.readObject();
    String data = frame.getData();
    System.out.println(data);
    // Send a string!
    DataOutputStream dos = new DataOutputStream (outputStream);
    dos.writeUTF("Received");
    dos.close();
    objectOutputStream.close();
    outputStream.close();
    objectInputStream.close();
    inputStream.close();
    socket.close();
}
