线程“main”java.lang.ArrayIndexOutOfBoundsException 中的异常：索引 0 超出长度 0 的边界，具有 RMI

问：

我有三个java文件，一个是RMI服务器和RMI客户端和接口文件，如下所示： 服务器：

import java.rmi.*;
import java.rmi.registry.*;
import java.rmi.server.*;
import java.net.*;

public class RmiServer extends 
  java.rmi.server.UnicastRemoteObject implements ReceiveMessageInterface{
  String address;
  Registry registry; 

  public void receiveMessage(String x) throws RemoteException{
  System.out.println(x);
  }
  
  public RmiServer() throws RemoteException{
  try{  
  address = (InetAddress.getLocalHost()).toString();
  }
  catch(Exception e){
  System.out.println("can't get inet address.");
  }
  int port=3233; 
  System.out.println("this address=" + address +  ",port=" + port);
  try{
  registry = LocateRegistry.createRegistry(port);
  registry.rebind("rmiServer", this);
  }
  catch(RemoteException e){
  throw e;
  }
  }
  static public void main(String args[]){
  try{
  RmiServer s = new RmiServer();
  }
  catch (Exception e){
  e.printStackTrace();
  System.exit(1);
  }
  }
}

客户：

import java.rmi.*;
import java.rmi.registry.*;

import java.net.*;

public class RmiClient{
  static public void main(String args[]){
  ReceiveMessageInterface rmiServer;
  Registry registry;
  String serverAddress=args[0];
  String serverPort=args[1];
  String text=args[2];
  System.out.println
   ("sending " + text + " to " +serverAddress + ":" + serverPort);
  try{
  registry=LocateRegistry.getRegistry
  (serverAddress,(new Integer(serverPort)).intValue());
  rmiServer=(ReceiveMessageInterface)(registry.lookup("rmiServer"));
  // call the remote method
  rmiServer.receiveMessage(text);
  }
  catch(RemoteException e){
  e.printStackTrace();
  }
  catch(NotBoundException e){
  e.printStackTrace();
  }
  }
}

接口：

import java.rmi.*;

public interface ReceiveMessageInterface extends Remote{
  void receiveMessage(String x) throws RemoteException;
}

所以基本上，当我运行服务器时，它会给我的笔记本电脑地址和正在运行的端口，这运行得很好 但是，问题是当我在运行服务器后运行客户端时，它不断抛出此错误：

线程“main”java.lang.ArrayIndexOutOfBoundsException中的异常： 索引 0 超出长度 0 的边界

哪个客户端文件在哪一行：

String serverAddress=args[0];
