Synopsis

This book introduces the JavaSpaces architecture, provides a definitive and comprehensive description of the model, and demonstrates how to use it to develop distributed computing applications. The book presents an overview of the JavaSpaces design and walks you through the basics, demonstrating key features through examples. Every aspect of JavaSpaces programming is examined in depth: entries, distributed data structures, synchronization, communication, application patterns, leases, distributed events, and transactions.

About this title

Review

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 atomize 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

From the Back Cover

"Ever since I first saw David Gelernter's Linda programming language almost twenty years ago, I felt that the basic ideas of Linda could be used to make an important advance in the ease of distributed and parallel programming. As part of the fruits of Sun's Jini project, we now have the JavaSpaces technology, a wonderfully simple platform for developing distributed applications that takes advantage of the power of the Java programming language. This important book and its many examples will help you learn about distributed and parallel programming. I highly recommend it to students, programmers, and the technically curious." Bill Joy, Chief Scientist and co-founder, Sun Microsystems, Inc.

JavaSpaces technology, a powerful Jini service from Sun Microsystems, facilitates building distributed applications for the Internet and Intranets. The JavaSpaces model involves persistent object exchange "areas" in which remote processes can coordinate their actions and exchange data. It provides a necessary ubiquitous, cross-platform framework for distributed computing, emerging as a key technology in this expanding field.

This book introduces the JavaSpaces architecture, provides a definitive and comprehensive description of the model, and demonstrates how to use it to develop distributed computing applications. The book presents an overview of the JavaSpaces design and walks you through the basics, demonstrating key features through examples. Every aspect of JavaSpaces programming is examined in depth: entries, distributed data structures, synchronization, communication, application patterns, leases, distributed events, and transactions.

You will find information on such vital topics as:

• Distributed data structures
• Synchronization techniques
• Loosely coupled communication
• Message passing
• Channel data structures for communication
• Application patterns such as replicated worker, command pattern, and marketplace
• Leases and automated lease renewal
• Using distributed events with spaces
• Handling partial failure with distributed transactions
• The official JavaSpaces specification from Sun Microsystems

JavaSpaces Principles, Patterns, and Practice also includes two full-scale applications--one collaborative and the other parallel--that demonstrate how to put the JavaSpaces model to work.
