Я пытаюсь отправить объект пользовательского класса через сокеты, но он выдает "java.io.NotSerializableException"

Ниже приведен пользовательский класс, объект которого я пытаюсь передать: 

    package dataEx;

    import java.io.Serializable;
    import java.util.*;

    public class dataToExchange implements Serializable
    {


        public Integer frameIndex;
        public Integer xOffsetTank;

    }

Соответствующий код клиента, где данные - это объект, который я пытаюсь передать, с помощью метода writeObject: 

    dataToExchange data=new dataToExchange() ;
    data.frameIndex=2;
    data.xOffsetTank=23;
    output.writeObject(data);

Сервер, принимающий объект и печатающий 

  data_recv=(dataToExchange)input.readObject();
  System.out.println(data_recv.xOffsetTank);

Трассировка стека:

Неправильный класс. Проверьте исключение еще раз. Вы пытаетесь сериализовать класс с именем «dataToExchange», определение которого вложено в класс «proclient» и не является сериализуемым. Вы упустили из виду, что у вас есть два класса с одним и тем же именем, что доказывает, что это плохая идея.
