Java cdc Personal Basis Profile (a subset of 1.4.2) doesn't have the
complete rmi implementation, nor does it have MarshalledObject (I'm sure
we can create our own implementation with a common interface and a
Static conversion class for Java SE).
Java Personal Basis Profile:

Java cdc (in the absence of JSR 66) is capable of serialising any class
instance where the bytecode is installed locally. It also has a
reflective proxy.
I'm considering using the OSGi mobile specification, (as part of a Java
cdc River Platform), in combination with JERI to download and
pre-install any absent compatible packages, dynamically on demand prior
to serialisation.
Making it possible for Java cdc to participate with compatible Jini
Services.
I think we need to create a new service lookup scheme, along the lines
of Gregg's recommendations, one suitable for the internet and the cdc
platform. I was thinking of creating a new interface, with a subset of
ServiceRegistrar's methods and inserting it before ServiceRegistrar in
the inheritance hierarchy (to have a simpler interface without breaking
compatibility), then extending our new interface to provide an
ObjectInputStream that returns MarshalledObjInstance's , it can't depend
on Java's built in MarshalledObject, so will have to make a static
factory utility class to return MarshalledObject or MarshalledInstance's
for Java SE. By using a stream, we can discard results we don't want,
without filling up our memory.
Cheers,
Peter.
