This article presents a middleware platform architecture whose goals, motivated by the needs of a real‐world application, are the following: separation of functional and non‐functional code in applications, composition of non‐functional properties, and modularity and extensibility of the middleware platform itself. This architecture is inspired by the Enterprise Java Beans platform, and uses a new object composition model to separate and compose the non‐functional properties. In order to evaluate this architecture, we have implemented the JavaPod platform which we have used to implement a prototype of the application that motivated our goals. The results of these experiments show that our goals can indeed be achieved with our architecture. Copyright © 2001 John Wiley & Sons, Ltd.
