The new xslt view supports an extensible Java XML adapter framework that makes it easy to customize the XML rendering of objects and to incorporate structured XML text and arbitarary DOM fragments into the output.

The XSLTResult class now uses an extensible adapter factory for rendering the Struts action Java object tree to an XML DOM for consumption by the stylesheet. Users can easily register their own adapters to produce custom XML views of Java types or simply extend a default "String" adapter and return plain or XML text to be incorporated into the DOM. The new adapter mechanism is capable of proxying existing DOM trees and incorporating them into the results, so you can freely mix DOMs produced from other sources into your result tree.

A default java.util.Map adapter is also now provided to render Maps to XML.

Please see the javadoc on the AdapterFactory for more details.
