rmic stub generation

[indo3]

Hello,
I have a question to Java RMI:
why does rmic need the Server Implementation class as input and
not can be satisfied with the inferface file? Since i thouhgt
the client just dont need to know anything about the "implementation"
of the remote object
but only about its interface.

Thanks

Because a remote object may implement more than one remote interface,
and its stub must do the same.

Ok but what IF its wanted that only one interface is exposed to one client,
another interface is exposed to another client for the same remote object,
since the remote object may hold the data base for both clients but both
clients want to use the object complete different (with different methods)?
Can this be modeled?

Sure, just cast Naming.lookup() to the desired interface in each case.
