Abstract. Software systems should evolve in order to respond to changing client requirements and their evolving environments. But unfortunately, the evolution of legacy applications generates an exorbitant cost. In this paper, we propose an approach to restructure legacy objectoriented applications into component-based applications. Our approach is based on dynamic dependencies between classes to identify potential components. In this way, the composition is dictated by the context of the application to improve its evolvability. We validate our approach through the study of three legacy Java applications.
