Abstract: Techniques that build distributed applications with reusable components are increasingly adopted. However, these components are developed by different programmers either in homogeneous or heterogeneous environments, with different methodology. It is hardly to build a robust and efficient system unless component dependency is clearly described. This paper represents a novel approach to describe the static component dependency. An event-based mechanism is also designed for dynamic change of component dependency. We have implemented a prototype using the proposed model. It has been shown that the approach combines both static and dynamic dependency.

Key words: component, componentbased distributed application, dynamic reconfiguration, dependency
