JavaSpaces Principles, Patterns, and Practice delivers an exciting introduction to the world of distributed, high-performance computing on Java's Jini platform using the new JavaSpaces API. Written for academic and business developers, this guide will help you begin using the Jini platform by outlining its powerful, elegant solutions for distributed computing.

After a foreword by distributed computing pioneer David Gelernter, the book provides a short technology overview describing the makeup of JavaSpaces. The authors atomise their description of JavaSpaces as an overseer application that lets programs running on separate computers store and share persistent data. While the JavaSpaces API is by itself remarkably simple, this book demonstrates with deliberate fanfare the resolution of common distributed computing problems using complex design patterns.

Early sections look at the basics of reading, writing, and searching for data stored in JavaSpaces as well as presenting task and result bags as solutions to managing work done in parallel. The book also elaborates on the readers/writers problem, well known within the field of computer science and even offers a means of addressing it. The authors use code samples from a chat message server and a model of a paging system using message channels during their discussion of message passing and communication with JavaSpaces.

One section on distributed patterns presents some common solutions to doing work in parallel, including the Marketplace pattern, illustrated with an e-commerce bidding application. Further sections cover distributed events and transactions as they apply to JavaSpaces. The book closes with two excellent examples, one for a distributed messaging service and another for a brute force attack on encrypted passwords.

With the debut of JavaSpaces, business developers gain access to distributed processing previously available only to academic researchers. The JavaSpaces solution, along with JavaSpaces Principles, Patterns, and Practice, will let any Java developer audition distributed computing for the first time. --Richard Dragan

This book helps understanding the Java Spaces and Jini 23. Januar 2000

Von Ein Kunde

Format:Taschenbuch

I read this book and I was very surprised about the technology and the large amount of examples in the book. This book explains the technology by examples and not by theory. The examples are explained in detail and it is quite easy to understand them and use them for your own applications. The examples are starting from low level to high level. I recommand this book to all people being interested in Jini and the Java Spaces. Read it, and enjoy it.

Very worth reading! 15. Januar 2000

If you want to create efficient distributed system with simple network programming ;-) Probably JavaSpace is one of the most efficient way to implement such system. The book is explaining such good system and some of it's implementations. There are various examples and all the book is written with a clear English language.

Many people were (including me) complaining about how to start these example programs in our computers. Now, a document is available in Java Developer Connection, that explains these steps. ).

I strongly recommend this book.

Great book! 9. Januar 2000

This is a great introduction to the JavaSpaces technology, making it accessible to anyone with a basic understanding of Java. The main concepts are thoroughly and simply explained and the programming examples are very well developed and easy to follow. This book would be suitable for introducing undergraduates to basic operating systems concepts such as process synchronization and interprocess communication, as well as to some of the more exciting network based applications, such as distributed transactions and collaborative applications.

It's clear that JavaSpaces technology can greatly simplify the teaching of important operating system and networking concepts such as thread synchronication and interprocess communication. As someone who has taught these courses, I've found that students have a hard time dealing with system semaphore and socket primitives. Quite often the basic concepts you're trying to teach get lost within a forest of implementation details. Not so with JavaSpaces. Check out the nicely developed Dining Philosophers and Readers/Writers examples in Chapter 4. The basic semaphore class is very simple to implement in JavaSpaces, which allows the discussion to focus on synchronization issues. Ditto for the basic Channel classes developed in Chapter 5. As all of these examples show, the use of JavaSpaces technology raises the level of abstraction, thereby making distributed programming much more widely accessible. As further evidence of this, consider the ease with which a very sophisticated internet messenger service is developed in Chapter 10. Making this kind of application accessible to undergraduates is quite impressive.

This is a great book, and I will almost certainly use it the next time I teach our networking course.
