Résumé
One of the main advantages of the Web component-based development paradigm is the ability to build customizable and composable web application modules as independent units of development, and to share them with other developers by publishing them in libraries as COTS (Commercial Off The Shelf) or free components. Besides this, since many years, Web services confirmed their status of the most pertinent solution for a given service provider, like Google, Amazon or FedEx, to open its solutions for third party development. In this paper, we present an approach to build web services starting from existing web component-based applications and deploy them on a web service provider. This transformation helps server-side web application developers in transforming their ”user interface”-based web components into a set of web services intended for remote code extensions. We implemented our solution on a collection of Java EE technologies.
