Hi, a question about RMI (I've at the start of my study)

I've found the feature of dynamic class downloading in RMI (using
RMIClassloader in RMI internals, I think).

Suppose I have a codebase defined as

-Djava.rmi.server.codebase="http://site1/A/ http://site2/B/"

I have a client that, according to this codebase, download classes from A
and B.

The question: Can a class x located in B have relationships with a class y
in A (x uses objects of y type)? In particular, can x extend y? Can the
RMIClassloader, in the client call, "resolve" an inheritance relationship
between remote locations?

Thanks, Andrea
