Halter begins by introducing JavaSpaces technology: This chapter shows you how some of the security features of Java can be currently used with JavaSpaces. The application presents a small ordering processing system. This book should provide a solid base with a coherent set of examples to lead people in the right directions for using JavaSpaces technology.

Piecing Together the Results. Other Technologies of Interest. 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. In a distributed application, JavaSpaces provides a shared virtual space that providers and requesters of objects can use to communicate easily.
Examples include using JavaSpaces as a mechanism for decoupled communication, application structuring, and parallel computing. This book should provide a solid base with a coherent set of examples to lead people in the right directions for using JavaSpaces technology. This should not be a surprising statement to anyone who has had to deal with a distributed programming environment in the past.
JavaSpaces technology is a simple mechanism for performing distributed computing. The application presents a small ordering processing system. JavaSpaces Example by Example offers an example-rich introduction to JavaSpaces architecture and its Jini network technology-based interfaces.
You then look at what an Entry is and how it can be used. Table of Contents Preface. Starting with the GUI. Halter Published Nov 9, by Prentice Hall. To compile the classes for the synchronization example in Windows, use the following. JavaSpaces Example by Example InformIT Next, he introduces the fundamental concepts of development, including entries, leasing, events, transactions, and persistence.
Preface Preface Writing distributed programs is hard. This chapter takes you through the process of installing Jini and JavaSpaces and running a simple application. This chapter is intended to establish exampoe and building blocks for these topics. Starting the Supporting Services. Description Copyright Dimensions: In particular, the introduction of JavaSpaces technology simplifies the distributed computing environment in several ways. Some common techniques for doing this, such as how to decide what computations could benefit from being distributed and how to distribute data, are discussed in this chapter.
Register your product to gain access to bonus material or receive a coupon. There are a number of ways to improve or degrade the performance of a distributed application. Parallel Computing in General. It covers a simple method of locating a single JavaSpace. That does not mean, however, that your application can have no security itself.
Getting a JavaSpace Running. Get unlimited day access to over 30, books about UX design, leadership, project management, teams, agile development, analytics, core programming, and so much more.
Exaample working knowledge of Java is needed, and an acquaintance with Jini concepts is very useful, but not required. In particular, some of the common problems, such as authorization configuration problems and improper codebase settings, are covered. Unlimited one-month access with your purchase. JavaSpaces also provides the ability to create and store objects with persistence.
There is currently edample standard Jini security model. JavaSpaces provides these capabilities with a very simple javaspaxes. Later chapters make greater use of these. Setting up policy files and using some simple protocols to aid in application level security are discussed. Useful Places for Information. TOP 10 Related.
Mamoud , 12, Technical Details Technical Article Building distributed applications is difficult because you must take into account several issues, such as partial failure, increased latency, distributed persistence, and language compatibility. The JavaSpaces technology is a simple and powerful high-level tool for building distributed and collaborative applications. Based on the concept of shared network-based space that serves as both object storage and exchange area, it provides a simple API that is easy to learn and yet expressive for building sophisticated distributed applications. This article provides a fast-track tutorial to the JavaSpaces technology, including An introduction to distributed computing An introduction to the JavaSpaces technology A comparison of JavaSpaces technology and databases A description of JavaSpaces services and operations The JavaSpaces technology application model The JavaSpaces technology programming model A flavor of the effort involved in developing applications using JavaSpaces technology Distributed Computing Distributed computing is about building network-based applications as a set of processes that are distributed across a network of computing nodes or hosts that work together to solve a problem. The advantages of building applications using this approach are many, including performance, resource sharing, scalability, and fault tolerance. But using distributed technologies does not guarantee these advantages. The developer must take special care in the design and implementation or distributed applications in order to achieve such benefits.
