When you build and deploy this modified Struts MailReader application, you'll see

that this page looks and behaves exactly as it does when implemented as a JSP page,

and no changes had to be made to any Struts actions or action forms.

The Velocity project site is located at http://jakarta.apache.org/velocity. From here,

you can download Velocity and the VelocityTools used in this recipe. You'll also find

several essays that compare Velocity to JSP and other page generation technologies.

14.10 Integrating Struts and XSLT

Problem

You want to use XSL transformations for HTML page generation instead of JSP

pages in your Struts application.

Solution

Use the STXX framework with Struts.

Discussion

The Struts for Transforming XML with XSL (STXX) framework was developed by

Don Brown. (The STXX project site can be found at http://stxx.sourceforge.net.)

STXX fits into Struts in a manner similar to Velocity. Instead of forwarding requests

to JSP pages, your action forwards to a special URL that is processed by the

StxxRequestProcessor

. Based on request data, this custom request processor reads a

configuration file to determine the corresponding XSLT stylesheet. The request pro 

cessor then uses an XSLT transformation engine to transform the received XML data,

using the XSLT stylesheet, into XHTML.

XHTML is HTML that is well formed, valid XML. XHTML is speci 

fied by the World Wide Web Consortium (W3C); details can be

found at http://www.w3.org/MarkUp/.

To get started, download STXX from the project web site (http://stxx.sourceforge.net).

This recipe was built using the full download of STXX Version 1.3. Extract the down 

load to your system.

Copy the following JAR files to your application's WEB INF/lib directory:

  dist/stxx 1.3.jar

  libs/core/jdom.jar

  libs/xform/commons jxpath 1.1.jar

  libs/xform/xmlform.jar
