Jini will be a focus of Activities in Java Grande Concurrency Group
http://www.sun.com/jini/ and also see very interesting Ninja project at UC Berkeley http://ninja.cs.berkeley.edu/
Jini is an innovative distributed computing capability with a classic 3 tier architecture with client, lookup service (called broker or server in other architectures) and service provider (the backend)
- There are four basic operations: Discovery, Join, Lookup, and Service Invocation
- Jini Services automatically register with Jini lookup servers and lease an entry there
Jini enables services to be dynamically linked to users of services
- It is a technology to produce a federation of linked clients and servers
Will carry us from collections of computers to enormous collections of devices -- the next Grande problem!
