Beginner running RMI example problem

Question

I am trying to test this RMI code from Thinking in java and it is giving this error
Exception in thread "main" java.lang.NoClassDefFoundError: DispatchPerfectTime (
wrong name: project3/rmi/DispatchPerfectTime)

I compiled the 3 files below and also called rmic and created a stub and skeleton..... Only it doesnt run..
Any ideas why ?
INTERFACE
package project3.rmi;
import java.rmi.*;
interface PerfectTimeI extends Remote
     long getPerfectTime() throws RemoteException;
}Implementation of Remote interface
package project3.rmi;
import java.rmi.*;
import java.rmi.server.*;
import java.rmi.registry.*;
import java.net.*;
public class PerfectTime extends UnicastRemoteObject implements PerfectTimeI
     public long getPerfectTime() throws RemoteException
          return System.currentTimeMillis();
     //constructor to throw remote exceptions
     public PerfectTime() throws RemoteException
          //super(); called automatically
     //register for rmi server
     public static void main(String args[]) throws Exception
          LocateRegistry.createRegistry(2005);
          System.setSecurityManager(new RMISecurityManager());
          PerfectTime pt = new PerfectTime();
     Naming.rebind("//200.23.23.2:2005/PerfectTime",pt); //I put dummy IP instead of my real IP
          System.out.println("Ready to do time");
}USING REMOTE OBJECT
/**Using the remote object**/
package project3.rmi;
import java.rmi.*;
public class DispatchPerfectTime
     public static void main(String args[]) throws Exception
          System.setSecurityManager(new RMISecurityManager());
          PerfectTimeI t = (PerfectTime)Naming.lookup("//200.23.23.2:2005/PerfectTime");
          for(int i =0;i<10;i++)
          System.out.println("Perfect Time is "+t.getPerfectTime());
}

I am just using another RMI example from class now...
All files are compiling but this is error.....
C:\>java -classpath c:\ RMIServer
Starting Server
Started Server...
Binding to RMI Registry
Error RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested excep
tion is:
java.lang.ClassNotFoundException: RMIServer_Stub
I doono if my host is correct...... I donno what to write in place of test... its some service??
import java.rmi.*;
import java.rmi.server.*;
import java.rmi.registry.*;
public class RMIServer extends UnicastRemoteObject implements RMIInterface
  static String host = "rmi://IPAddress/test";
  static String data[] = {"c","c++","java"};
  public RMIServer() throws RemoteException
            super();
  //implement methods
  public int getNumData() throws RemoteException
            return data.length;
  public String getData(int index) throws RemoteException
          if(index>=0 && index<data.length)
               return data[index];
          else
               return "N/A";
  public static void main(String args[])
       RMIServer server;
       try{
            System.out.println("Starting Server");
            server = new RMIServer();
            System.out.println("Started Server...");
              System.out.println("Binding to RMI Registry");
            Naming.rebind(host,server);
            System.out.println("Remote methods registered successfully");
       catch(Exception e){
            System.out.println("Error "+e.getMessage());
  }//main
} //class
