Where are Parser Classes?

Question

Hello,
I hate to be new, but I am. I am running jdk1.3.1 and I working out of the xml tutorial. I have a simple java class that is including the following classes:
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.w3c.dom.Document;
import org.w3c.dom.DOMException;
// For write operation
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
When I try and compile this class (classpaths are all good) my system says it cannot resolve symbol for class Transformer, TransformerException, TransformerFactory, etc.
I don't know where to find these classes? Don't they come with the standard j2se? If not where do I go for them?
Thanks

Those classes are part of the api JAXP. You can download the sun implementation here : http://java.sun.com/xml/downloads/javaxmlpack.html or Apache's one with Xerces (http://xml.apache.org).
They are also included with the j2se but the 1.4 version : http://java.sun.com/j2se/1.4/docs/api/index.html
