Useful Places for Information. It covers a simple method of locating a single JavaSpace. Some common techniques for doing this, such as how to decide what computations javawpaces benefit from being distributed and how to distribute data, are discussed in this chapter. Starting the Supporting Services. Using Leases with JavaSpaces. Getting and Installing Jini. 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.

To compile the classes for the synchronization example in Windows, use the following. The intended audience is for intermediate to advanced programmers wanting to learn about JavaSpaces.

JavaSpaces provides these capabilities with a very simple interface. Although an experienced Jini developer may skip this chapter, for beginners, this should be extremely valuable. Effectively making use of the simple interface, however, requires a number of tools, both conceptual and practical. Add To My Wish List. Obtaining and Installing JavaSpaces.

In it, you also briefly encounter some jafaspaces the ways JavaSpaces are being used and might be used. Distributed programming is different than programming within a single machine process. Book Sorry, this book is no longer in print.

JavaSpaces Example by Example InformIT This should not be a surprising statement to anyone who has had to deal with a distributed programming environment in exam;le past. This chapter takes you through the process of installing Jini and JavaSpaces and running a simple application.

There is currently no standard Jini security model. Setting up policy files and using some simple protocols to aid in application level security are discussed. Core Technologies, 2nd Edition. Other Technologies of Interest. Preface Preface Writing distributed programs is hard.

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. This chapter covers some of the exampld involved with programming in a distributed environment. A working knowledge of Java is needed, and an acquaintance with Jini concepts is very useful, but not required. Exa,ple 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.

Examples include using JavaSpaces as a mechanism for decoupled communication, application structuring, and parallel computing. Later chapters make greater use of these.

Technical Article

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.

Object Spaces[ edit ] Object Spaces is a paradigm for development of distributed computing applications. It is characterized by the existence of logical entities, called Object Spaces. All the participants of the distributed application share an Object Space. A provider of a service encapsulates the service as an Object , and puts it in the Object Space.
