Exploiting dynamic proxies in middleware for distributed, parallel, and mobile Java applications

Babylon v2.0 is a collection of tools and services that provide a 100% Java compatible environment for developing, running and managing parallel, distributed and mobile Java applications. It incorporates features like object migration, asynchronous method invocation and remote class loading while providing an easy-to-use interface. The implementation of Babylon v2.0 exploits dynamic proxies, a feature added to Java 1.3 that allows runtime creation of proxy objects. This paper shows how Babylon v2.0 exploits dynamic proxies to implement several key features without the need for special language or virtual machine extensions, preprocessors, or compilers. The resulting Babylon programs are portable across all Java virtual machines, and the development process is simplified by removing the extra steps needed to invoke external stub compilers and incorporate the generated code into an application. This simplification also allows remote objects to be created for any class that supports an interface to its methods, even if source code is not available
