RE: Unable to transform to docbook

You know what... 

It might be a problem with the includes but to be honest I would have expected another exception in that case. Is there any way you can share the sources for the project so I can adjust the dev.properties file for my situation and crack the problem?  I'm sure I will find out quickly but helping out by mail is a bit more tedious to be honest.

So if you can provide me with a zip file containing the project and the docbook xslt's zipped and perhaps also that ex.xml file I can debug your issue.

Yes, exactly ! The first one is failing, the second one is working. So the issue is only with docbook.xsl being processed from cocoon.

I tried both matchers and they seem to be working fine. I can do http://localhost:8888/transform/docbook.xsl and I get the expected output.
The docbook.xsl has a lot of <xsl:include> :

<?xml version="1.0" encoding="UTF-8"?><xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ng="http://docbook.org/docbook-ng"

xmlns:exsl="http://exslt.org/common"
xmlns:exslt="http://exslt.org/common" exclude-result-prefixes="db ng exsl exslt" version="1.0">

<xsl:output method="html" encoding="ISO-8859-1" indent="no"/>
