Re: What's SOAP got to do with it?
Yes, you're right. I didn't realize the scope of the dependencies the
static methods in XMLUtils have on the rest of the axis code. I placed
all the jar files from the axis distribution in the shared directory,
and no more NCDFEs. (I moved just saaj.jar at first, but I got other
NCDFEs, so I moved all the axis jars.)
But now I'm getting fatal SAXParser errors when I try to ingest HTML
4.01 documents that are not well-formed XML. Xerces has implemented HTML
DOM, but apparently there's no support for creating HTMLDocumentImpl
objects from an InputStream serving an HTML 4.01 document.

Mark,
use JTidy for consuming HTML it supports handling non-well-formed
documents. Another choice is CyberNeko HTML Parser
http://people.apache.org/~andyc/neko/doc/index.html based on Xerces
XNI.
