Systems and techniques for using a Web-service based business process to interact with a Web browser as if the Web browser were a Web service server. In one exemplary implementation, an interface module with a HTTP server is provided to convert data from the Web browser into an XML document from a Web service server and to convert data from the business process engine in an XML document to a Web service server into a Web page for the Web browser. The business process engine may be programmed in the Business Process Execution Language for Web Services (BPEL) or other suitable business process execution languages.
