Eclipse and Web Services

Web Services are the most promising SOC-based technology. They use the Internet as the communication framework and open Internet-based standards, including Simple Object Access Protocol (SOAP) for transmitting data, the Web Services Description Language (WSDL) for defining services, a lot of visual tools for representing web services (ex. Protège), and the Business process Execution Language for Web Services (BPEL4WS) for orchestrating services. The Eclipse platform is the ideal platform to sustain a WS approach given that SOC group together many intricately concepts, protocols and technologies that originate in a wide range of disciplines. Many Eclipse projects are ongoing actually in the Eclipse platform, but one of most interesting challenges is represented by the logical composition of web services. This paper shows the state of the art of this projects, sustained from Eclipse Italian community, and shows a tool developed into eclipse environment that aims to compose web services in a logical manner. The same approach will be used in e-learning composing, in a logical manner, educational artefact, in order to satisfy a request
