Abstract. Adapting software components to be used in a particular application is a crucial issue in software component based technology. In fact, software components can be used in contexts with characteristics different from those envisaged when designing the component. Centralized or distributed deployment infrastructure can be one of these assumptions. Thus, a component can be designed as a monolithic unit to be deployed on a centralized infrastructure, nevertheless the used infrastructure needs the component to be distributed. In this paper, we propose an approach allowing to transform a centralized software component into a distributed one. Our technique is based on refactoring and fragmentation of component source code.

We present in this paper an approach aiming at dynamically adapting a component structure while preserving its behavior and its services. Among the motivations of this kind of adaptation, we note its possible application to allow a dynamic redeployment of component services according to the available resources (e.g. CPU, memory). The run-time software component structural adaptation process is based on two phases. The first one consists in transforming this component by generating a dynamically adaptable component structure. This transformation is based on the analysis and the instrumentation of component code. The second phase of the adaptation process allows us to adapt the component dynamically by the reconfiguration of its internal structure.
