Abstract

In The Mythical Man Month, Frederick P. Brooks Jr. followed the lead of Aristotle and divided all of software technology into the realms of "essence" and "accidents." To the seasoned Jini developer, CLASSPATH environment variables, RMI codebases, Java security policies, and Jini URLs are common facets associated with the design and implementation of distributed systems. However, the Jini novitiate is often confounded and frustrated by the "accidents" that are normally associated with the implementation of distributed systems in Jini. In this presentation we highlight some of the current limiting factors of the Jini "out of the box" experience. Moreover, we present a platform independent utility for starting a complete Jini environment, including the JavaSpaces service. Written entirely in Java, this utility contains support for benchmarking JavaSpaces service implementations and it can be used as a replacement for the Tonic tuple-space benchmarking tool. While this simple utility can be used from the command-line to start a Jini environment, it can be programatically invoked with standard Java programming language constructs from a client class. We believe that our simple tool can improve the Jini development experience for beginners and experts alike.
