That is not the easiest of questions to answer. When Sun, or more precisely, Jim Waldo, brought out Jini, there was a lot of verbal traffic about it in the Java community. JavaSpaces I believe preceded Jini but got adopted by the Jini East Coast mob as an early Sun Orphan. Rumour has it that the J2EE mob on the West Coast for some strange reason looked on J/JS as dangerous competition, and so used their proximity to the Sun tin-bashers who ran the company to do down J/JS in favour of their own comprehensive, simple, easy-to-use architecture......
I must stress that this rumour is gossip, and no, I have no hard evidence to back it up. I understand that it is true that in the over 70% of alleged cases of J2EE users chewing to eschew EJBs, the combination of servlets and J/JS can provide an intersting alternative. On my J/JS Group there is an ancient list of companies providing implementations in one form or another: http://groups.yahoo.com/group/jini_javaspaces/database?method=reportRows&tbl=2 A lot of companies who developed J/JS solutions subsequently decided to use it as an engine in their later offerings. I think you will find this applies to GigaSpaces, Sun and IntaMission. Gregg, what is your information on present users/implementers? Funnily enough with the rise of the New Generation of distributed computing (SOA/BPM et al.) there is renewed interest in Jini for reasons which Gregg has explained clearly over the last few months.
