Cannot cast xmlReader to Parser

Question

I'm trying to parse XML file with SAX following this tutorial on Maven project. Here's my SAXLocalNameCount:

 public class SAXLocalNameCount extends DefaultHandler {
        private static String filename = ".\\file.xml";

    public static void main(String[] args) throws ParserConfigurationException, org.xml.sax.SAXException, IOException, SAXException {

    SAXParserFactory spfactory = SAXParserFactory.newInstance();
        spfactory.setNamespaceAware(true);
        SAXParser saxParser = spfactory.newSAXParser();
        XMLReader xmlReader = saxParser.getXMLReader();
        xmlReader.setContentHandler(new SAXLocalNameCount());
        xmlReader.parse(convertToFileURL());

    }

    private static void usage() {
        System.err.println("Usage: SAXLocalNameCount <file.xml>");
        System.err.println(" -usage or -help = this message");
        System.exit(1);
    }
    private Hashtable tags;

    public void startDocument() throws SAXException {
        tags = new Hashtable();
    }

    public void startElement(String namespaceURI,
                             String localName,
                             String qName,
                             Attributes atts)
            throws SAXException {

        String key = localName;
        Object value = tags.get(key);

        if (value == null) {
            tags.put(key, new Integer(1));
        }
        else {
            int count = ((Integer)value).intValue();
            count++;
            tags.put(key, new Integer(count));
        }
    }

    public void endDocument() throws SAXException {
        Enumeration e = tags.keys();
        while (e.hasMoreElements()) {
            String tag = (String) e.nextElement();
            int count = (Integer) tags.get(tag);
            System.out.println("Local Name \"" + tag + "\" occurs "
                    + count + " times");
        }
    }
    private static String convertToFileURL() {
        String path = new File(filename).getAbsolutePath();
        if (File.separatorChar != '/') {
            path = path.replace(File.separatorChar, '/');
        }

        if (!path.startsWith("/")) {
            path = "/" + path;
        }
        return "file:" + path;
    }

}

This line:

XMLReader xmlReader = saxParser.getXMLReader();

gives me error:

ClassCastException: org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser cannot be cast to jdk.internal.org.xml.sax.XMLReader

What am I missing here?

Answer 1

My problem was that I was importing from jdk.internal.org.xml.sax.helpers.DefaultHandler and the right import was supposed to be org.xml.sax.helpers.DefaultHandler
