Default XML-parser implementation?

[Martin Egholm Nielsen]

Hi there,

I've been browsing around the archives for this subject, but I don't 
seem to be able to find the answer.
Browsing the libgcj.jar archive I've noticed that the "javax.xml.*" 
packages are not present, so I cannot use the 
"javax.xml.parsers.SAXParserFactory" class.
So I turned to the "org.xml.sax.helpers.XMLReaderFactory"-class instead 
(which I noticed was in jar-archive).
It compiles fine, however, when I try to execute I get the error:

Exception in thread "main" org.xml.sax.SAXException: Can't create 
default XMLReader; is system property org.xml.sax.driver set?

And to that question I have to admit: No!
Therefore I ask: Is there an implementation available, or need I turn to 
e.g. Xerces?
