public class SaxXml {
// 重载DefaultHandler类的方法
    // 以拦截SAX事件通知。
    //
         // 关于所有有效事件，见org.xml.sax.ContentHandler
    //
    public void startDocument( ) throws SAXException {

    }

    public void endDocument( ) throws SAXException {
       System.out.println( "SAX Event: END DOCUMENT" );
    }

    public void startElement( String namespaceURI, String localName, String qName, Attributes attr ) throws SAXException {
          System.out.println( "SAX Event: START ELEMENT[ " +
                   localName + " ]" );

       // 如果有属性，我们也一并打印出来．．．
                 for ( int i = 0; i < attr.getLength(); i++ ){
                    System.out.println( "   ATTRIBUTE: " + attr.getLocalName(i) + " VALUE: " + attr.getValue(i) );
       }

}

    public void endElement( String namespaceURI, String localName, String qName ) throws SAXException {
       System.out.println( "SAX Event: END ELEMENT[ "+localName + " ]" );
    }

public void characters( char[] ch, int start, int length )
throws SAXException {

System.out.print( "SAX Event: CHARACTERS[ " );

       try {
          OutputStreamWriter outw = new OutputStreamWriter(System.out);
          outw.write( ch, start,length );
          outw.flush();
       } catch (Exception e) {
          e.printStackTrace();
       }

System.out.println( " )" );

}

public static void main( String[] argv ){

System.out.println( "Example1 SAX Events:" );
try {

// SAXParserFactory spFactory = SAXParserFactory.newInstance();
// SAXParser sParser = spFactory.newSAXParser();

// 建立SAX 2解析器．．．
XMLReader xr = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");

// 安装ContentHandler．．．
xr.setContentHandler( new SaxTest() );

             // 解析文件．．．
          xr.parse( new InputSource(
                new FileReader( "exampleA.xml" )) );

       }catch ( Exception e )  {
          e.printStackTrace();
       }

}

xr.setContentHandler( new SaxTest() );
报错说找不到SaxTest这个类请问这个类在哪个包里面啊？
