Newly enhanced with the latest standards from Sun,
Core Jini, 2nd Edition, provides an in-depth and authoritative resource for building state-of-the-art distributed systems based on Jini v. 1.1. Aimed at the experienced Java developer seeking to apply this technology in the field, this book mixes a high-level guide to what Jini is and how it works with plenty of practical code examples to help get you started.
The first part of Core Jini describes what Jini is, including its design philosophy and how it provides robust distributed systems for devices like printers, scanners, and digital cameras. Suitably upbeat about Jini's prospects in the marketplace, the author delivers an insider's perspective on how Jini solves many of the problems of earlier distributed computing. The first hundred pages will help anyone understand Jini and are especially ideal for programmers (or managers) who want to see what this standard is all about.
The rest of the text (over 800 pages) provides a practical tutorial that puts Jini to work, starting with a "Hello World" example. Subsequent chapters cover essential areas of Jini functionality, such as discovery, leasing, and the join protocol. Besides providing actual source code, the book does a good job of showing how to compile and run each example program. (This information is particularly necessary with Jini, where even for testing, programs run in separate pieces in a small distributed system.) Core Jini teaches you the most common programming strategies for Jini (relying on higher-level APIs and built-in features), and also shows the lower-level APIs in separate sections for the more advanced reader who wants to know more.
Armed with this new edition, any Java developer can learn to take advantage of this late-breaking technology from Sun. In all, this title is a comprehensive and well-presented tutorial to an exciting, new standard that will allow future consumer and computing devices to communicate using Java. --Richard Dragan
Amazon.co.uk Review
While Jini promises to be a potential rival to CORBA and DCOM for general distributed development, the focus of Core JINI is on using the technology to connect peripherals to networks via Java.
Traditional problems found in distributed computing--and how Jini overcomes them--are tackled first. After this overview comes a simple "Hello World" example as well as a solid guide to setting up and running the Jini tools. Then the book delves into Jini specifics starting with "discovery" (which allows devices to find Jini services on the fly). The book explains in detail how Jini services advertise themselves using both multicast and unicast protocols.
Jini services are "leased" by clients; a section on Jini's leasing protocol shows the details from both the server- and client-side. All of the requirements for a 'well-behaved' Jini service are summarized, along with a complete example for a print service. Core JINI gives the working Java developer all necessary technical information to get this done. --Richard Dragan
