A Service-Oriented Componentization Framework for Java Software Systems

In the fast growing global market for services, service-oriented computing has drastically changed the way in which we develop software systems. Providing competitive services to these markets will be critical to the success of businesses and organizations. Some competitive services have already been implemented in existing systems. In this paper, we present a novel service-oriented componentization framework that automatically supports: i) identifying critical business services embedded in an existing Java system by utilizing graph representations of the system models, ii) realizing each identified service as a self-contained component that can be deployed as a single unit, and iii) transforming the object-oriented design into a service-oriented architecture. A toolkit implementing our framework has been developed as an Eclipse rich client platform (RCP). Our initial evaluation has shown that our framework is effective in identifying services from an object-oriented design and migrating it to a service-oriented architecture
