XSLT Servlet

This servlet transforms an XML document using an XSLT stylesheet. Probably there are other Servlet implementations of this kind, but I couldn’t find one with the features I need available under an Open Source license, so I wrote this one.

Features

• the XML document and the stylesheet can be retrieved from the local webapp or from the network (using java.net).
• Stylesheet is preloaded at startup and then periodically reloaded in the background in order to optimize performance.
• JSP EL expressions can be used in the Servlet init params.
• Parameters can be passed to the stylesheet.
• XSLT output properties can be controlled by the Servlet.
• Not tied to a specific XML parser or XSLT processor.
  This Servlet uses javax.xml.transform (aka TrAX) for XSLT processing.

This is a sample web.xml configuration:

<servlet>
  <servlet-name>myTransformation</servlet-name>
  <servlet-class>it.kataweb.xslt.servlet.XSLTServlet</servlet-class>
  <init-param>
    <param-name>xml</param-name>
    <param-value>http://domain.org/service?param=${param.myParam}</param-value>
  </init-param>
  <init-param>
    <param-name>xslt</param-name>
    <param-value>/WEB-INF/xslt/myStylesheet.xslt</param-value>
  </init-param>
  <init-param>
    <param-name>xsltReloadInterval</param-name>
    <param-value>60</param-value>
  </init-param>
</servlet>

For reference documentation see the Javadocs included in the distribution.
