我想通过socket发送自定义类的对象，但它抛出“java.io.NotSerializableException”

以下是自定义类，它的对象我试图通过：我想通过socket发送自定义类的对象，但它抛出“java.io.NotSerializableException”

package dataEx; 

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

    public class dataToExchange implements Serializable 
    { 


     public Integer frameIndex; 
     public Integer xOffsetTank; 

    }

相关客户机代码，其中所述数据是一个对象我试图通过，通过writeObject方法：

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

服务器接收所述对象和打印

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

堆栈跟踪：

错误的类。再次检查异常。您试图序列化一个名为'dataToExchange'的类，该类的定义嵌套在类'proclient'内，而不是Serializable。你忽略了你有两个同名的班级，这在这里被证明是一个坏主意。

你是对的！非常感谢你。多么愚蠢，我最初为服务器和客户端分别创建了dataToExchange，然后我发现一个普通类应该在那里，但是随后在ctrl-zeding代码中，我忘记删除以前的dataToExchange副本。为我服务，我应该更多地关注堆栈跟踪，看到它的大小，我只是略过它，现在我知道它的重要性。再次感谢你，结束了我的沮丧，因为我刚刚开始使用套接字，你帮了我很多。 – 2012-03-29 13:55:20
