Sun's Jini may turn out to be one of the most important technologies of the next decade: a smarter way to network systems without the hassles we've come to accept as inevitable. Xerox PARC researcher W. Keith Edwards was one of the first people outside Sun to discover Jini, and he's just written a remarkably accessible, helpful guide for anyone who wants to develop with it.
All too often, the "first" book on a subject is rushed sloppily to market, but not this time. Edwards truly understands Jini, and CORE JINI does an exceptional job of explaining why it's so important, not only for "non-traditional" devices (which get the hype), but also for enterprise computing (where the money is).
One of the key challenges standing in the way of distributed systems has been the fundamental difference between local and remote systems: in a nutshell, remote systems can fail in all sorts of ways that local systems do not. Traditional approaches to distributed computing try to paper over the distinction, with mixed success. Jini addresses it head on — and Edwards explains how, in-depth. You'll master key Jini concepts such as discovery, Jini's Landlord Paradigm, remote events, and transactions; learn how to build lookup services and lookup service browsers; walk through writing leases and managing lease negotiation; even learn how to work with JavaSpaces, a powerful service built atop Jini which enables high-performance distributed and parallel computing.
The book has been thoroughly vetted by Sun insiders Brian Murphy and Peter van der Linden. There's lots of code, anditruns (what a concept)!
If you're already familiar with Java—and, ideally, at least a bit familiar with RMI—you'll find Jini surprisingly easy to master. Especially if you learn it with W. Keith Edwards' CORE JINI. — Bill Camarda,
