Can not initialize XML parser

Question

Can someone say how to initialize a SAX parser?
When I try to do it, a SAXException occures.
I think thats because no paser driver is loaded (as API docs say).
How can I make it work?

Try the following snippet (not compiled) with JDK 1.3 or higher (crimson included) to get the idea:
class DummyContentHandler implements org.xml.sax.ContentHandler{
        int count = 0;
        public void startDocument() throws org.xml.sax.SAXException {}       
        public void characters(char[] values, int param, int param2) throws org.xml.sax.SAXException {}       
        public void ignorableWhitespace(char[] values, int param, int param2) throws org.xml.sax.SAXException {}       
        public void processingInstruction(java.lang.String str, java.lang.String str1) throws org.xml.sax.SAXException {  }
        public void startPrefixMapping(java.lang.String str, java.lang.String str1) throws org.xml.sax.SAXException {}
        public void endDocument() throws org.xml.sax.SAXException {}
        public void skippedEntity(java.lang.String str) throws org.xml.sax.SAXException {}
        public void setDocumentLocator(org.xml.sax.Locator locator) {}
        public void endPrefixMapping(java.lang.String str) throws org.xml.sax.SAXException {}
        public void startElement(java.lang.String str,
          java.lang.String str1,
          java.lang.String str2,
          org.xml.sax.Attributes attributes) throws org.xml.sax.SAXException {
            count++;
        public void endElement(java.lang.String str,
               java.lang.String str1,
               java.lang.String str2) throws org.xml.sax.SAXException {}
  public class SAXer{
  // Helper method
  public static void parseWithSax(org.xml.sax.InputSource is,org.xml.sax.ContentHandler ch) throws Exception{
          javax.xml.parsers.SAXParserFactory spf =
            javax.xml.parsers.SAXParserFactory.newInstance();
          spf.setNamespaceAware(true);
          org.xml.sax.XMLReader p = (org.xml.sax.XMLReader)spf.newSAXParser().getXMLReader();  
          p.setContentHandler(ch);
          p.parse(is);
  public static void main(String[] args) throws Exception{
       // Set factory
       System.setProperty("javax.xml.parsers.SAXParserFactory", "org.apache.crimson.jaxp.SAXParserFactoryImpl");
       // Initialize content handler
        DummyContentHandler ch = new DummyContentHandler(); 
       String test = "<a><b/></a>";
       parseWithSax(new org.xml.sax.InputSource(new java.io.StringReader(test)),ch);
        System.out.println("Elementcount:" + ch.count);
  }
