Your assumptions are correct. the nbsp is not in the dtd. I get
javax.xml.transform.TransformerException: org.xml.sax.SAXParseException:
The entity "nbsp" was referenced, but not declared. at
org.apache.xalan.transformer.TransformerIdentityImpl.transform(TransformerIdentityImpl.java:502)
I am using xerces 2.9.1 and xalan 2.7.1
When i do
XMLReader r = XMLReaderFactory.createXMLReader();
URL u =
r.getClass().getClassLoader().getResource(r.getClass().getName().replace('.',
'/') + ".class");
System.out.println(u);namespace aware or
i get
jar:file:/home/dave/dev/tomailer/war/WEB-INF/lib/xercesImpl.jar!/org/apache/xerces/parsers/SAXParser.class
which is the jar i'm expecting to get the parser from.
the is in PCDATA.
Do i need to specify that the parser is validating in order to get this
to work, perhaps?
thanks again.

Looks about right.

Is "nbsp" declared in your DTD? You said your goal was to "resolve
unknown entities" so I'm assuming it's not declared.
Is this entity reference part of an attribute value? If it is you're
out of luck with SAX. skippedEntity() as well as the entity methods on
LexicalHandler are never called for attributes.
Also can you double check that you're actually using a recent release
of Xerces-J and not its JDK fork or NekoHTML or something else.
