Re: Replacing JRMP with JERI

Depends what you mean.  The RMI registry remote object created by the
"rmiregsitry" tool or the LocateRegistry.createRegistry API is always
exported with JRMP, meaning that you can only communicate with it
using JRMP (possibly with custom socket factories).  You can still
register JERI stubs/proxies in it, though, if the necessary libraries
are in its class path.

Note that this RMI registry implementation is just a very simple
remote object, essentially a hash table that maps strings to
serializable objects that are instances of java.rmi.Remote, with some
simple client-IP-based access control.  What's special about it is
that it gets exported with a "well-known" java.rmi.server.ObjID, so
that a bootstrap stub can be created for it by a client, which is done
using the LocateRegistry.getRegistry API (or indirectly through the
java.rmi.Naming API).

The JERI API provides a public way to export any remote object with
the JERI equivalent of a "well-known" object ID[*] and to conjure a
stub/proxy for such an exported object, so it would be straightforward
to implement an "RMI registry" equivalent (perhaps even supporting the
same java.rmi.registry.Registry interface) that uses some form of JERI
for communication.  The Jini starter kit does not include code that
does this because the expectation is that using a Jini lookup service
would be more desirable anyway, but I just mention this to note that
it would be simple to have a JERI-based "RMI registry".
