    Abstract

    This paper presents a comprehensive comparison of the architectural differences and similarities of the two most popular Java-based distributed object models: RMI and CORBA. Performance and timing issues related to the CORBA and RMI architectures are also considered. The following aspects are studied for client server applications, on Sun UltraSparcs under Solaris 2.5.1 and Pentium II under Windows NT 4.0: response time for method invocation without parameters as well as with variable number of parameters; response time for applet clients, and response time for variable number of clients requesting the same service. The goal is to provide a reference framework that supports the selection of either mechanism for the development of web-based distributed real-time applications: chat programs, interactive games, shared boards, etc.
