Re: Is Jini Dead? Where do I find useful documentation?

Jini is not dead. It has moved to Apache and is now called River.
http://incubator.apache.org/river/RIVER/index.html

I don't know enough Jini to solve your Exception problem, sorry. Try the
River mailing lists.
It sounds like a policy problem or SecurityManager problem. You probably
want a "grant all permissions" in there somewhere if it is not already there
(or something to that effect). But again, the River mailing lists will be a
lot more helpful than my random bablings.

Good hunting!
