I recall Gregg as (sort of) advocating Jini over both, WS-* and REST
</Jan>

There no "sort of" with Gregg and Jini :-) But his advocacy has made me
curious enough to pick up a book on Jini to explore the technology
because there are some particular use cases where a SOA implemented
using Jini may indeed be viable. But to borrow a phrase from Steve,
there is a degree of "formalism" around Jini that allows me to wrap my
head around it.>>

Group at:

It strikes me that when looking for technologies in which to implement
SOA, people are beginning to discover, or rediscover the virtues of
Jini. When choosing a suitable technology for SOA, Web Services and
REST seem the main contenders, CORBA being looked on as a mainly
legacy technology. Jini, however is perceived as having a place in
the SOA scheme of things. Gergg has done more than whole marketing
departments to argue Jini's case. I think he deserves some sort of
marketing advocacy medal from Sun, or at least a fat salary and a
chauffeur-driven Rolls-Royce Phantom as Jini Envangelist :).

It would be very interesting to hear of case studies using
Jini/JavaSpaces with or without, say, Web Services to implement a SOA
structure.

Any volunteers?
