I'm looking at how we do parsing and looking at
XmlFileLoader.LocalErrorHandler.
It looks like errors are ignored if the schema wasn't resolved. Is this
the way to do it?

How do you set up xml parsing to not validate if there is no schema

HEM is doing the following code and throwing an error:
private static Document loadURL(URL configURL, EntityResolver
resolver) throws Exception {
InputStream is = configURL != null ? configURL.openStream() : null;
if ( is == null ) {
throw new IOException( "Failed to obtain InputStream from
url: " + configURL );
}
List errors = new ArrayList();
DocumentBuilderFactory docBuilderFactory = null;
docBuilderFactory = DocumentBuilderFactory.newInstance();
docBuilderFactory.setValidating( true );
docBuilderFactory.setNamespaceAware( true );
try {
//otherwise Xerces fails in validation
docBuilderFactory.setAttribute(
"http://apache.org/xml/features/validation/schema";, true);
}
catch (IllegalArgumentException e) {
docBuilderFactory.setValidating( false );
docBuilderFactory.setNamespaceAware( false );
}
InputSource source = new InputSource( is );
DocumentBuilder docBuilder =
docBuilderFactory.newDocumentBuilder();
docBuilder.setEntityResolver( resolver );
docBuilder.setErrorHandler( new ErrorLogger("XML InputStream",
errors) );
Document doc = docBuilder.parse( source );
if ( errors.size() != 0 ) {
throw new PersistenceException( "invalid persistence.xml",
(Throwable) errors.get( 0 ) );
}
return doc;
}
