Re: jaxp 1.4 on jre 1.4.2

I am trying to use the jaxp1.4 standalone download from java.net with
Sun JRE 1.4.2. Here is a minimal test class:

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;

import org.w3c.dom.Document;

public class TestJaxp {
   public static void main(String[] args) throws Exception {
           Document doc = DocumentBuilderFactory.newInstance()
                           .newDocumentBuilder().newDocument();
           XPath xpath = XPathFactory.newInstance().newXPath();
           xpath.evaluate("/", doc);
   }
}

It fails with:

java.lang.NoClassDefFoundError: com/sun/org/apache/xalan/internal/
extensions/ExpressionContext
My classpath consists of this class followed byjaxp-api.jar thenjaxp-
ri.jar.
