Java RMI - 如何從客戶端發送回調對象

我正在使用RMI，我有Server Client程序。Java RMI - 如何從客戶端發送回調對象

客戶端從服務器訪問某些方法。

但是，在我想傳遞一個客戶端本地對象的方法之一中，使用其參考服務器將執行回調（這將在客戶端執行），至少這是我想要的，但可能是我在做它錯了。

在客戶

--------------------------------------------------------------------------------- 
    server.setLock("/hello.txt", 99, 125,Locker.Lock_type.WRITE,"Shubham Verma",true, new CallBackProcess()); 
--------------------------------------------------------------------------------- 

CallBackProcess implements an interface which is presented on both the ends. 

But I get this error
