Unfortunately I can't do much with them. What I meant was a 
self-containing minimal example that I can run. E.g. some stupid parsing 
or transforming. A XML HelloWorld if you like...

So, I just tested the:
SAXTransformerFactory factory = (SAXTransformerFactory)
		SAXTransformerFactory.newInstance();

And I need this to get it working:

static
{
	gnu.xml.dom.ls.SAXEventSink.class.getName();
	gnu.xml.transform.TransformerFactoryImpl.class.getName();
	gnu.xml.xpath.XPathFactoryImpl.class.getName();
	org.xml.sax.ContentHandler.class.getName();
}

Please read the very small "Step 1 of 4: Source" part in the manual to 
understand why this is necessary. Maybe you need more of them for other 
XML stuff too...
I'd still appreciate a minimal XML HelloWorld if you have time. Attached 
and not inlined if possible :-)


Hope it helps...
