An idea of automatic construction of Web applications from templates has already been proposed by Jamroendararasame et al. (2001, 2002) and Taguchiet al. (2002). A software system called T-Web system has been implemented based on the idea to automatically generate typical Web applications made of various technologies such as CGI, Java servlet, JSP, and ASP, without manual programming. This paper presents an extension of the above mentioned idea in two different areas, construction of Web services and construction of Web applications that behave as Web services requestors. Based on T-Web system for JSP/servlet Web applications (Jamroendararasame et al., 2002), we implement the T-Web system that provides features for Web developers to design and generate Web services written in Java language, typical JSP/servlet Web applications, and JSP/servlet Web applications behaving as Web services requestors.
