商品描述

  • The hands-on, example-rich guide to JavaSpaces technology
  • Building robust, scalable, high-performance distributed applications
  • Up-to-the-minute coverage based on Jini 1.1 network technology and JDK 1.4 software
  • Practical solutions to the most common challenges of distributed development

The example-rich guide to JavaSpaces technology: building more robust, scalable, and secure distributed applications for working developers!

JavaSpaces technology simplifies distributed computing, by providing a shared virtual space where tasks, requests, and information can easily be exchanged in the form of objects based on Javatm technology. JavaSpaces Example by Example offers an example-rich introduction to JavaSpaces architecture and its Jini network technology-based interfaces. Using this book's extensive examples and projects, experienced developers can begin building applications using the JavaSpaces specification almost immediately—and quickly master advanced techniques for enhancing security, performance, and scalability.

Steven L. Halter begins by introducing JavaSpaces technology: its goals, advantages, applications, and current capabilities. He walks you through obtaining, installing, and configuring JavaSpaces architecture, addressing common problems such as authorization configuration and improper codebase settings. Next, he introduces the fundamental concepts of development, including entries, leasing, events, transactions, and persistence.

You'll learn powerful distributed programming techniques, including the effective use of data structures and collections; and better ways to improve performance, prevent deadlock, and take full advantage of parallelism. Halter provides in-depth coverage of scalability and availability, concluding with detailed guidance on using security features based on Java 2 technology to protect distributed JavaSpaces applications.

Extensive code examples illustrate:

  • Leasing and events
  • Transactions and persistence
  • Jini technology interfaces
  • Performance optimization
  • Data structures
  • Collections
  • Preventing deadlock
  • Maximizing parallelism
  • Distributed application security
  • Improving scalability
