A diagram approach toautomatic generation of JSP/Servlet Web applications

We defined diagrams called Web transition diagrams to represent overall behavior of Web applications. Using these diagrams, we can generate server program type Web applications such as CGI-based Web applications, and server page type Web applications such as ASP-based Web applications. The purpose of this paper is to design Web transition diagrams to represent wider class of Web applications based on JavaServer Pages (JSP)/Servlet architecture. Then we present an automatic generation method of JSP/Servlet Web applications from these diagrams. We implement a software system called T-Web system which enables Web application designers to visually compose Web transition diagrams and generate Web applications from these diagrams without any manual programming. T-Web system can generate both H^™L-based Web pages and XML-based Web pages for Web applications. Generated Web applications support standard level of security against attacks, the use of HTTP cookies, user authentication, and session management.
