我想建立一个RMI服务器，我试过这样
package first_project;
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.util.ArrayList;
public class Server extends UnicastRemoteObject implements ServerInterface {
// list for know users
protected ArrayList<ClientInterface> clients = new ArrayList<ClientInterface>();
public Server() throws RemoteException {}
//logged in clients get a notification that a new user has joined the chat
// remote reference to the new client is added to the ArrayList.
public void login(ClientInterface client, String nickname) throws RemoteException {
broadcastMessage("--> " + nickname + " is entering the chatroom", "");
clients.add(client);
}
// used for broadcasting an incoming message
// and the nickname of its sender to all currently logged in clients .
//remote call of the method getMessage which is
public void broadcastMessage(String message, String nickname) throws RemoteException {
for (int i = 0; i < clients.size(); i++) {
ClientInterface c = clients.get(i);
try {
c.getMessage(message, nickname);
} catch (RemoteException e) {
logout(c);
i = i - 1;
} }}
//remove user
public void logout(ClientInterface client) {
clients.remove(client);
}
public static void main(String[] args) {
try {
Naming.rebind("Server", new Server());
System.out.println("Server is ready");
} catch (Exception e) {
e.printStackTrace();
}
}
}
但我不知道为什么我得到这个异常：

请问我做错了什么？
