Setting up SAX and Crimson

Question

Hello.
Thanks in advance for any help or advice.
I am trying to parse XML. I have done a bit of background reading and made a few attempts - but i am stuck.
I would like to parse XML using Crimson. I would like to use SAX as the API to that parser (hope i have got things correct so far?).
I instanciate my parser as follows:
import org.xml.sax.*;
import org.xml.sax.helpers.XMLReaderFactory;
import javax.xml.parsers.*;
// this code is in a class called ClientXMLParser
try
               SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
               try
                    saxParser = saxParserFactory.newSAXParser();
               catch( ParserConfigurationException e )
                    System.out.println( "Error: " + e );
               gameXMLParser = new GameXMLParser();
               xmlReader = XMLReaderFactory.createXMLReader();
          catch( SAXException e )
               System.out.println( "Error: " + e );
          }I have another class that acts as my hanlder class:
import org.xml.sax.helpers.DefaultHandler;
public class GameXMLParser extends DefaultHandler
     public GameXMLParser()
          super();
     public void startDocument()
          System.out.println( "Start document" );
    public void endDocument()
         System.out.println( "End document" );
}So this is pretty much all i have at the moment.
I understand that i have to have:
1) A SAX2-compatible XML parser installed on your Java class path.
(I chose Crimson and just put the .jar in my jdk lib directory).
How do i know that my SAX API knows about my XML parser.
I am confused about the overall structure of how to set things up. I thought all i needed was SAX, Crimson and Java?
I am not parsing a File - but i construct a file out of Strings and just want to parse the XML document as a string, (it is sent from Macromedia Flash):
serverData += '<?xml version="1.0" encoding="utf-8"?>\n';
          serverData += '<flashClient id="' + 123456 + '">\n';
          serverData += '<getPlayers />\n';
          serverData += '</flashClient>\n';Regards, Sam
