Abstract

Web Services (WS) enable access to remote applications over the Internet. Composition thereof gives rise to more complex services by integrating applications over borders of companies, institutions, and countries. But such compositions fail if they cannot dynamically adapt to change in such an ever changing environment. Unfortunately web compositions today are still implemented in a static way. Implementing invocations of web services is too verbose and heavy-weight. It requires manual extraction of each service's information from interface descriptions and because of the missing transparency in composition languages, developers repetitively have to write low-level invocation code. This paper proposes a light-weight approach for automatic and transparent web service compositions, supporting standard SOAP-based web services. We provide a proof-of-concept as a scripting language. The benefit is that our web services composition approach makes compositions simpler and more transparent, because invoking a web service is no more complicated than invoking a local method.
