TraX not validating my document?

[William Lee <wl...@sendmail.com>]

I seem to have a problem trying to use the DocumentBuilder to validate
my document using a DTD.  When I try the following:

DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance();
dfactory.setValidating(true);
DocumentBuilder dbuilder = dfactory.newDocumentBuilder();
Document doc = dbuilder.parse([some uri]);

However, it doesn't seem to work.  My XML file has the doctype defined:

<!DOCTYPE someroot SYSTEM "someroot.dtd">

and when I violate the someroot.dtd in the xml document, I don't really
get an error.  Why is this?

You're really just using Xerces here, Xalan is not involved.  So, your
question really belongs on the Xerces mailing list.  However, the
chances are the you are validating but you haven't supplied an
ErrorHandler.  In that case, all of the errors will invoke the default
ErrorHandler which probably just ignores them.  Have a look at the
org.xml.sax.ErrorHandler interface and make your own simple error
handler and the call dbuilder.setErrorHandler() with it.
