AOP for Dynamic Configuration and Management of Web Services

We observe that current approaches for the integration of Web services hard-wire the service references into client applications, affecting adaptability and reusability. Moreover, support for client-side management is hardly provided. To enable the development of more flexible and robust applications we propose the Web Services Management Layer (WSML). In this article we identify the requirements for the WSML to realize dynamic integration, client-side service management, and support for service criteria to govern the selection, integration and composition of Web services. We show how dynamic AOP, and in particular the dynamic aspect-oriented language JAsCo, is ideally suited to implement the core functionality of the WSML.
