A Jini and RMI problem: Class is not a valid remote interface

i've been trying to compile stubs for a Jini example i have to run but can't

rmic -d D:\JUSTIN~1\sampledir\EXPERI~1\ch9 -classpath D:\JUSTIN~1\sampledir EXPERIMENTS.ch9.JINIConnectorImpl

it gives me errors:

EXPERIMENTS.ch9.JINIConnecterImpl is not a valid remote interface: method java.lang.Integer getMBeanCount() must throw java.rmi.Exception

EXPERIMENTS.ch9.JINIConnecterImpl is not a valid remote interface: method javax.management.ObjectInstance createMBean() must throw java.rmi.Exception

You need to define that those methods throw java.rmi.Exception as stated in error message.

I have a class JINIConnectorException..

package EXPERIMENTS.ch9;

import java.rmi.*;

public class JINIConnectorException extends RemoteException
{
public Exception exception = null;
public JINIConnectorException( String message, Exception ex )
{
super( message, ex );
this.exception = ex;
}

public Exception getWrappedException()
{
return exception;
}
}

it is inherited by this class ..
---------------------------------
package EXPERIMENTS.ch9;
import java.rmi.*;
import javax.management.*;
import EXPERIMENTS.ch9.JINIConnectorException;
public interface JINIConnector extends Remote
{

public Integer getMBeanCount() throws JINIConnectorException;
public ObjectInstance createMBean(String className,
ObjectName name) throws JINIConnectorException;}
---------------------------------

so in effect my understanding is that the methods still retain their java.rmi.Exception types (sorry im a newbie)
so i don't get why the rmic compiler is giving me the errors.

So i should do away with the subclass JINIConnectorException and just declare

public Integer getMBeanCount() throws RemoteException
public ObjectInstance createMBean(String className,
ObjectName name throws RemoteException;}

I believe so.

i got to revise the code but it still gave me errors.. anyway i went back to the site where i got the example. Luckily it had the revised code so its compiling now but with more errors. The rmic has been giving me a javax.management.<class> not found.
