I've tried it both ways around, to no avail :/

Yeah - same occoured to me, but I think I've now found the

Would have done first time around, but I've got a small problem
at the moment - Copy and paste is currently dead in my copy of
X. More than a little annoying, that ;)

The AbstractMethodException is occouring in org.apache.xalan.
utils.DOMBuilder.startElement, which is line 275 in my version
(from yesterday's CVS, I think). The line in question is:

  elem = m_doc.createElementNS(ns,name);

I put a tracer in there to find out what class m_doc is, and
I get a huge list of org.apache.xalan.stree.DocumentImpls which
all process fine, and then a single com.sun.xml.tree.XmlDocument.

I have no idea how a com.sun.xml.tree.XmlDocument is even getting
created by Cocoon - the only jaxp parser installed is Xerces.

I'm now trying to track down where the class is getting loaded,
but I'm having other problems when I try to use the latest Xerces.

I'll let you know if I get anywhere.
