Abstract

Many servlets do nothing more than integrate data from multiple sources to create an XML or HTML result. As an XML-oriented data integration language, XQuery is a particularly simple, productive, and efficient way to do this task. In this presentation, we show a servlet that provides a REST interface to any XQuery that a developer places in a secure deployment directory on an application server, then demonstrate the development of data services by writing XQueries that access XML, relational, and flat file formats such as EDI to create complex XML and HTML results, then copying to the deployment directory.
