@Override
public InputSource resolveEntity(String publicId, String systemId) {
return new InputSource(MyUtilityClass.class.getResourceAsStream(“logger.dtd”));
}

And set the entity resolver of the parser to the instance of your utility class (eg, “this”).

final SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
saxParserFactory.setValidating(false);
final SAXParser saxParser = saxParserFactory.newSAXParser();
final XMLReader parser = saxParser.getXMLReader();

parser.setEntityResolver(new EntityResolver(){
	public InputSource resolveEntity(String publicId, String systemId) {
		return new InputSource(new ByteArrayInputStream(new byte[]{}));
	}
});

To make Xerces ignore the DTD, just after you’ve created the XMLReader (assigned to parser in my example above), you set the two features shown and then it ignores the DTD (but obviously this means that it won’t check to ensure that the XML conforms to it).

That’s all you have to do.
