Missing xpath method error from some classpath disaster or another

I can provoke the following by trying to use Xalan inside of a Webapp
inside of Tomcat after using the JAXP 1.4 explicit newInstance to
obtain my factory. Confused doesn't begin to describe my reaction. Can
anyone give me a clue? Or a diagnostic procedure?

java.lang.NoSuchMethodError: org.apache.xpath.XPathContext.<init>(Z)V
        org.apache.xpath.jaxp.XPathImpl.eval(XPathImpl.java:207)
        org.apache.xpath.jaxp.XPathImpl.evaluate(XPathImpl.java:281)
        org.apache.mtomcatbug.Serviette.doGet(Serviette.java:58)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:627)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

Benson,

  This could happen if Tomcat is bundling a different version of Xalan  
than the one you used to compile your webapp. You should check that.  
You can always bundle your own version of Xalan if classloading is set  
to support that in Tomcat. The Tomcat user list may be able to help  
you with that.
