Looks great, but doesn't this mean a less efficient system - ie isn't it
going through a number of extra steps to arrive at thge same functionality?

This can be implemented as a logicsheet and you'll forget about pure Java
in
your XSPs and have much clear XSP pages. More over, if you develop a
transformer for this then you'll be able to apply it even to pure XML
files.
This way a logicsheet can be used:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsp:page
language="java"
xmlns:xsp="http://apache.org/xsp";
xmlns:sax=http://anyhost/xmlize/1.0
>
<xsp:logic>
<![CDATA[
Jbxsp jbxsp;
int id = -1;]]>
</xsp:logic>
<page>
<sax:to-sax src="request"
attribute="com.jpmorgan.mih.intranet.example.SimpleSite" />
</page>
</xsp:page>
And the transformer version:
<?xml version="1.0" encoding="ISO-8859-1"?>
<page xmlns:sax=http://anyhost/xmlize/1.0>
<sax:to-sax src="request"
attribute="com.jpmorgan.mih.intranet.example.SimpleSite" />
</page>
and use this sitemap configuration:
...
<map:match pattern="*.xml">
<map:generate src="files/{1}.xml"/>
<map:transform type="xmlize" />
<map:serialize />
</map:match>
Of course, you should also declare your transformer in <map:transformers >
section.
Just my <i18n:currency value="0.02" />
