XTP (XML Template Pages) enhances JSP pages with stylesheets. Sophisticated projects can split page formatting from the JSP-generated content. Splitting the graphic design from the JSP programming helps a web site in several ways:

How XTP works

XTP Copy

For most XTP pages, the default XSLT transormation you want is to copy the input into the output.

Formatting

A major advantage of XTP is its separation of content from formatting. Your source documents can use meaningful markup tags letting the stylesheet format the output.

Link Rewriting

XTP can be used to rewrite links.

JSP tag libraries with XSL

XML Template Pages encourages web sites to create JSP tag libraries. By putting the JSP creation in stylesheets, you can separate the programming from the web pages.

StyleScript

'StyleScript' adds some syntactic sugar to XSLT to make stylesheets more readable.

Tag Libraries

XTP Template Pages can be used to create JSP tag libraries.

Templates

This example uses a servlet filter to select the stylesheet that is used for XTP pages.
