On the subject of misunderstanding RMI - I do a lot of talks, coaching,
mentoring etc in respect of Jini and RMI and have observed the following:
Most developers equate RMI to RMI(IIOP) not RMI(JRMP). RMI(JRMP) is the
original RMI with the IIOP based implementation (and all its
compromises) coming later. This seems to be related in some way to the
widespread use of EJB app servers where RMI(JRMP) was eschewed in favour
of RMI(IIOP).
The result is most developers are under the impression that stubs must
be generated up front and available on client classpaths in similar
fashion to the way most will have used CORBA. They aren't aware of
things such as code downloading or codebases.

Dan.
