RMI客戶com.sun.proxy.Proxy無法施展錯誤

Question

服務器：

package server; 

import java.rmi.*; 
public interface iCSServer extends Remote 
{ 
    public int Findnumber(int num) throws RemoteException; 
} 


package server; 

import java.rmi.Naming; 
import java.rmi.RemoteException; 
import java.rmi.registry.LocateRegistry; 
import java.rmi.server.UnicastRemoteObject; 

而且

public class CSServer extends UnicastRemoteObject implements iCSServer { 
    private static final long serialVersionUID = 01; // version 01 
    int N=1000; // number of ids 
    int[] Ids=new int[N]; // data structure for storing the Ids 
    public CSServer() throws RemoteException 
    { 
    } 
    public void Add_Ids() // add ids to data 
    { 
     for(int i=0;i<N;i++) 
     { 
      Ids[i]=i+ (i+1)*10; 
     } 
    } 
    public int Findnumber(int num) throws RemoteException 
    { 
     for(int i=0;i<N;i++) 
     { 
      if(num==Ids[i]) 
      { 
       return i; 
      } 
     } 
     return -1; 
    } 
    public static void main(String[] args) throws RemoteException { 

     System.setProperty("java.rmi.server.hostname","127.0.0.1"); 
     LocateRegistry.createRegistry(1099); 


     // System.out.println(LocateRegistry.getRegistry(1099).toString()); 

     CSServer obj=new CSServer(); 
     obj.Add_Ids(); 

     try { 
      Naming.rebind ("CSServer", obj); 
      System.out.println ("CS218 Server is running."); 
     } 
     catch (Exception e) { 
      System.out.println ("CS218 server cannot run: " + e); 
     } 
    } 
} 

服務器啓動並運行良好。

客戶：

package client; 

import java.rmi.Remote; 
import java.rmi.RemoteException; 
import java.rmi.*; 

public interface iCSServer extends Remote 
{ 
    public int Findnumber(int num) throws RemoteException; 
} 

而且

package client; 

import java.rmi.Naming; 
import java.rmi.registry.*; 
public class clientApp { 
    public static void main(String[] args) 
    { 



     try{ 
      iCSServer obj = (iCSServer) Naming.lookup("//localhost:1099/CSServer"); 
      //Registry registry = LocateRegistry.getRegistry("127.0.0.1"); 
      //iCSServer obj=(iCSServer) registry.lookup("CSServer"); 

      System.out.println("pass"); 
      System.out.println(obj.Findnumber(100)); 
     } 
     catch(Exception ex) 
     { 
      System.out.println("fail"); 
      System.out.println(ex.getMessage()); 
     } 
    } 
} 

然而，當我運行客戶端我得到這個錯誤：

fail 
error unmarshalling return; nested exception is: 
java.lang.ClassNotFoundException: server.iCSServer (no security manager: RMI class loader disabled) 

然後我添加的服務器的jar'd版本.ICSServer，我相信解決這個問題。然而，我再次運行它，現在我得到這個錯誤：

fail 
com.sun.proxy.$Proxy0 cannot be cast to client.iCSServer 

任何想法如何解決？

您已將接口重命名爲不同的包。它必須是相同的。
