A Wrapping Approach and Tool for Migrating Legacy Components to Web Services

While legacy systems are becoming incompatible with Service-oriented computing, it is a challenging task for migration of component based legacy systems towards service-oriented applications. In this paper, a black-box modernization approach is proposed to make components that compose legacy systems accessible as Web Services by a wrapper. The wrapper tool is used for interacting with legacy systems and Service-oriented systems acts as a mediator. Our strategy also proposes a standard process that constructs the wrapper tool by black box reverse engineering techniques. Finally, the tool is applied to a case study for showing process effectiveness and quality of wrapped services.
