Middleware Service Support for Modern Application Presentations

Abstract

Nowadays, with steadily increasing number of various markup languages and their dialects, application developers need more often to rewrite the presentation in order to support more client devices. Java programmers using JSP for dynamic generation of the presentation layer have to create for given content different Java Server Pages (JSP)´s for showing it in different HTTP, WAP and Palm client. Instead of rewriting the same JSP several times, authors demonstrate an approach of separation of content and presentation form, by means of XSLT transformation over XML content. The client device type is detected by a server-side detector, which uses the type for choosing the correct XSLT for the correspondent XML content generated by a JSP. Moreover, for non-XML browsers, the detector invokes a transformer, which generates on-the-fly any-ML presentation using both the XML and XSLT.
