Providing easier access to remote objects in client-server systems

The Java Environment for Distributed Invocation (JEDI) is efficient, dynamic and easier to use than alternative communication systems for distributed Java objects. Existing state-of-the-art mechanisms for remote method calls on Java objects, such as RMI (remote method invocation), require users to perform a complicated series of steps. Furthermore, the compiled static interfaces these systems use limit their functionality. This paper presents the design and implementation of JEDI´s simpler approach utilizing dynamic proxies. We discuss a means of integrating JEDI with a publicly available CORBA object request broker (ORB), followed by the tests used to ensure the robustness of the JEDI system. Comparing this system´s performance with that of other communication facilities such as UDP, TCP and RMI demonstrates the efficiency of JEDI. A calendar program illustrates the flexibility and usability tradeoffs of employing JEDI in distributed client-server applications
