Make DocumentBuilder.parse ignore DTD references

When I parse my xml file (variable f) in this method, I get an error

C:\Documents and Settings\joe\Desktop\aicpcudev\OnlineModule\map.dtd (The system cannot find the path specified)

I know I do not have the dtd, nor do I need it. How can I parse this File object into a Document object while ignoring DTD reference errors?

private static Document getDoc(File f, String docId) throws Exception{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(f);

return doc;

A similar approach to the one suggested by @anjanb

    builder.setEntityResolver(new EntityResolver() {
        public InputSource resolveEntity(String publicId, String systemId)
                throws SAXException, IOException {
            if (systemId.contains("foo.dtd")) {
                return new InputSource(new StringReader(""));
            } else {
                return null;

I found that simply returning an empty InputSource worked just as well?
