When designing an XML-based Web Content Management System (WCMS), one usually has to define and maintain two separate entities just for the editorial part: the database schemes (in form of XML Schema instances) on the one hand and the graphical user interfaces (GUIs) for data maintenance on the other hand. In this paper we present a method for generating the GUIs automatically from the XML Schema instances, thus the GUI can be specified in a declarative, implicit way. The target platform is Java Swing. Our transformation is based on compile-time generated templates and the XML persistence feature of Java 2.
