Abstract: Web services, together with serviceoriented architectures, are promising integration technology to facilitate legacy system webification and evolution. However, a service oriented reengineering process is still essential for legacy systems to survive in the serviceoriented computing environment. In this serviceoriented reengineering process, understanding and reusing objectoriented code turn to be important activities. In this paper, we proposed a comprehensive approach to support the extraction and integration of reusable objectoriented legacy code. It produces extracted components with core objectoriented legacy code function in Web services by wrapping underlying computing models with XML.
