Semi-Automatic Code Generation of Static Web Services Composition

Current composite Web service planning and designing solutions based on contemporary process modeling languages (BPEL4WS, BPML, WSCI, etc.) are very much a manual activity which require specialized knowledge of these languages and take up much time and effort. Moreover business processes are changing constantly which require businesses to be agile. The business people who deal with these changing processes are not highly trained in technology which forces them to depend on developers or technologist to make the changes. This causes delayed adaptation and long run loses. In this paper we propose a method to semi-automatically generate Web service composition in BPEL4WS language. Our system captures minimal most necessary information from the user and stores it in a relational model. Later transformation algorithm is applied to map the relational model to BPEL4WS model. By applying this approach much detail of the language constructs is abstracted from the user.
