我已经为RMI的客户端编写了以下代码。但是得到

java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused: connect

代码：

import java.rmi.*;
import java.net.*;
import java.rmi.registry.*;
class client
{
    public static void main(String [] ars)
    {
        Iface serv;
        Registry r;
        String serveraddr = ars[0];
        String serverport = ars[1];
        String text = "Hey jude";
        System.out.println("Sending" + text);
        try{
            r = LocateRegistry.getRegistry(
            serveraddr,
            (new Integer(serverport)).intValue()
            );
            serv = (Iface) r.lookup("rmi://server");
            serv.receive(text);
        }
        catch(Exception e){
            System.out.println(e);
        }
    }   
}
