Implementing Web access includes finding a Web module and a Web module method associated with a client request. Based on a parameter declaration of the Web module method, a Web server obtains from a Web context request data that is used to invoke the Web module method. The Web server then stores in a Web context a return value and renders a displayed Web page based on the Web context. In some aspects, implementing Web access further includes analyzing the parameter declaration of the Web module methods and finding a data scope and a data item associated with the request data. In some aspects, implementing Web access further includes generating a Web module instance in response to determination that the instance does not exist.
