rmi compliation problem

i took it form a different angle (because i found a different tutorial ,by David Reilly)

i added the methods defined in the interface to the server

i compiled the server

then i wanted to compile it with rmic to get the stubs

and it returned an error

D:\JAVA_P~1\SIMPLE~2>rmic -classpath . -iiop -idl PhoneDirServer

error: java.rmi.server.RemoteServer is not a valid remote implementation: has no

remote interfaces.

1 error

sorry the code is

import java.rmi.*;

import java.rmi.server.*;

import java.io.BufferedReader;

import java.io.FileReader;

import java.util.HashMap;

import java.util.Map;

public class PhoneDirServer extends UnicastRemoteObject

implements PhoneDirInterface {

private Map pbMap = new HashMap();

public PhoneDirServer () throws RemoteException

{

super();

try {

BufferedReader br = new BufferedReader(new FileReader("numbers.txt"));

String line;

while ((line = br.readLine()) != null)

{

String[] info = line.split(":", 2);

pbMap.put(info[0], info[1]);

}

}

catch (Exception exc) {

exc.printStackTrace();

System.exit(1);}

}

public String getPhoneNumber(String name) {

return (String) pbMap.get(name); }

public boolean addPhoneNumber(String name, String num) {

if (pbMap.containsKey(name)) return false;

pbMap.put(name, num);return true; }

public boolean replacePhoneNumber(String name, String num) {

if (!pbMap.containsKey(name)) return false;

pbMap.put(name, num);return true;

}

public static void main ( String args[] ) throws Exception

{

// Assign a security manager, in the event that dynamic

// classes are loaded

if (System.getSecurityManager() == null)

System.setSecurityManager ( new RMISecurityManager() );

// Create an instance of our service server ...

PhoneDirServer server = new PhoneDirServer();

// ... and bind it with the RMI Registry

Naming.bind ("PhoneBook",server);

System.out.println ("Service bound....");

}

}

and the interface is

import java.rmi.Remote;

import java.rmi.RemoteException;

/**

* This is an interface to a component that looks up

*

*/

public interface PhoneDirInterface extends Remote {

public String getPhoneNumber(String name) throws RemoteException;

public boolean addPhoneNumber(String name, String num) throws RemoteException;

public boolean replacePhoneNumber(String name, String num)throws RemoteException;

}

this would mean that the tutorial is not well written :(

because in the tutorial Server extends UnicastRemoteObject

i removed UnicastRemoteObject

but when i run the server i get

D:\JAVA_P~1\SIMPLE~2>java PhoneDirServer

Exception in thread "main" java.rmi.MarshalException: error marshalling argument

s; nested exception is:

java.io.NotSerializableException: PhoneDirServer

and when i run the client i get :((

here is the server code
