Product Description A guide for programmers to the formal specification for the core Jini connection technology, and specifications for local helper utilities and remote helper services. Every specification is described in detail, from device architecture to semantics. Previous edition: c1999. Softcover. DLC: Electronic data processing.
Amazon.com Review What does Sun's Jini technology mean for the future of distributed computing? To find out, take a look at The Jini Specification, a guide written for IS managers and Java developers alike. The book starts with what Jini is and how it works. (In short, Jini allows Java clients to invoke remote services easily through Java.) The authors present a chat message server and explain the Jini architecture where clients look up and "lease" remote services. The heart of this book is its coverage of classes in the Jini specification. First there's an overview of Jini illustrated with a printer service. Then it's a close look at how clients "discover" Jini services, either through multicast or unicast protocols. (The authors also present useful built-in utility classes here.) Next comes material on storing entries for Jini services (used for identifying them across the network) and the classes used to "lease" remote services. An interesting section on remote events contrasts them with local JavaBean events. Then it's on to Jini transactions, including the two-phase commit process used to manage work done remotely. Later the book turns to the new JavaSpaces classes, which permit sharing data between Java processes in order to facilitate parallelism. An intriguing appendix reprints a white paper in which the Sun team outlines its philosophy of distributed computing. (They argue that local and remote objects need to be handled differently: object location transparency is a myth.) With a mix of technology briefing and nuts-and-bolts detail, The Jini Specification delivers a valuable perspective on the latest advance in Java distributed computing from Sun. --Richard Dragan

  More than a Specification August 18, 2001 1 out of 1 found this review helpful
I put off buying this for about a year because I was fooled by the title. Think of it as a primer on how to use Jini the way the people who developed Jini intended (rather than as a spec). That makes it very useful. Not ideal for someone who is considering using Jini and wants an overview, but a great "second book" on Jini. Similar to Keith Edwards' Jini "Example by Example".
  Good but lacking June 19, 2000 3 out of 4 found this review helpful
Since it has so many glowing reviews, I'll give it a review that may be uselful to the authors for future additions.I don't understand why Sun Microsystems, on their website and in thier books, (and this book is no exception) do not use UML to describe their libraries and frameworks. I, for one, learn a lot about dependencies and collaborations between classes when UML is employed. In the sections that have real code examples, it would be helpful to have a snippet of UML describing the section of Jini critical to that example, for instance. Furthermore, in the earlier sections of the book, the overview, the authors use what I call "system collaboration diagrams", even better would be when they are explaining code snippets to highlight in their system collaboration diagrams what part of the system they are showing an example of. I guess I just found the explaination of the examples lacking. The examples themselves are excerpted, making them hard to follow. For instance, it is confusing to see an ordinary method being called (from within an excerpt) with no class or object qualified before it. Is it in the superclass? In the implementation? If in the superclass, how far up? This is especially difficult when referring to the DEM of Java, which sometimes seems counterintuitive to beginners. My rule of thumb is one should never look at a piece of code and get "nervous" about what a symbol or method is supposed to be doing there.
  Excellent guide and reference for Jini developers November 30, 1999 17 out of 17 found this review helpful
Jini has to be about the hottest new Java technology to be released in years. Imagine a world of plug-and-play networked devices, which can be installed and seamlessly integrated with your LAN simply by connecting them to your network. A laptop on-the-go can just plug in to an unfamiliar network, and access the printer or Internet proxy server, without the need to install any drivers. Mixing Unix and Wintel devices? Not a worry. Jini promises to let them talk to each other. That's the vision behind Jini. But that vision goes much further. Not only can hardware devices talk to one another, but also software services. In a Jini world, you won't care whether how a device works, or whether it is software or hardware based. An Internet based fax service will act as a fax, as will a hardware device. You'll just look for a fax service, without worrying how the service is implemented. Of course, someone needs to write the software that will power Jini services. That's where The Jini Specification comes in. The book is divided into two main sections, an overview and the specification for Jini. The overview provides an easily accessible overview of what Jini is, how it works, and what it can achieve. There are also several examples of Jini services and clients, to give you some practical experience with building Jini software applications. From there, the book dives headfirst into the actual specification. The first part of the book is good for managers, and software developers alike. The coverage of the specification, however, is designed as a reference for developers as they construct Jini software. This is where many readers could become lost, unless they are already using Jini in action. The first part of the book is a guide to Jini, the second intended only as a reference during development. Finally, a glossary of Jini terms and an essay on distributed computing is included, along with the full source code from the overview. The Jini Specification is a must-have for anyone considering Jini development. It provides an excellent guide to Jini technology for those considering designing Jini-based systems, and a comprehensive printed reference for those who will implement them. -- David Reilly, for the Java Coffee Break
  Best book for knowing latest in distributed computing July 21, 1999 4 out of 4 found this review helpful
As a distributed computer designer, developer and research I feel this book is best for JINI - which is the latest and modest happening in field of distributed computing. The book not only covers JINI specifications, but has a clear theory on what it is, with code samples and very clean writing fashion. Moreover, it is short and to the point. I strongly recommend this book to distributed design professionals and students, as it gives a latest tech flavour for them to be in touch and know tommorrows' computing arena.
  Extremely Comprehensive and Well Written June 30, 1999 This book deals with a complicated subject in an intelligent and well organized manner. The excellent presentation itself speaks well for the quality of the editing provided by the publisher, and I highly recommend it for anyone involved in the field.
