MECHANISMS FOR SUPPORTING BACK BUTTON FUNCTION OF WEB BROWSER AS WEB SERVICE SERVER IN INTERACTION WITH BUSINESS PROCESS ENGINE

This application describes 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. Mechanisms for supporting the back button function in the Web browser are described for interaction between the business process engine and the Web browser.
