Hi,

I have to implement an RMI instant messaging application in Java for a
class project.  I was given a stub to work with.

In the remote interface there is a method that like this that
registers the client with the server:

void register(RegistrationInfo reg) throws RemoteException;

My question is, where do I put the RegistrationInfo class?  I have to
create a RegistrationInfo object on the client side, but then when I
call the remote method, it complains that it doesn't know what a
RegistrationInfo object is.  Where do I put this class?

Thanks very much for your help.
