Hey,
Jini could be viewed as an advanced Java RMI but what about JavaSpaces?
How JavaSpaces differs from Jini?
Doesn't JavaSpaces implement Google's MapReducde?

1. *Jini could be viewed as an advanced Java RMI but what about JavaSpaces?
- JavaSpaces is built on a JINI framework, probably the widest use of JINI

2. *How JavaSpaces differs from Jini?
- See above - Jini is the general communication framework

3. *Doesn't JavaSpaces implement Google's MapReducde?
- You could use JavaSpaces to implement the so called "Map/Reduce" approach to distributed computing, it is a general tool for communication between multiple computers.

Would you please suggest a couple of cases where JavaSpaces could fit?
It seems it is so powerful technology, why we don't see it in the industry (except for GigaSpaces)?

See this article for my take on where Javaspaces fits in the "Grid" computing picture.

It seems it is so powerful technology, why we don't see it in the industry (except for GigaSpaces)?



Why would you expect a casual glance to show where it is used "in industry."
