Exception when using Xalan in Servlet to produce an html-response:org.w3

I use newest xalan and jaxp-version and tried to transform xml to html in a servlet.

This exception occured:

java.lang.NoSuchMethodError: org.w3c.dom.Node: method getLocalName()Ljava/lang/String; not found
        at org.apache.xalan.templates.TemplateList.getHead(TemplateList.java:471)

        at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:2894)
        at java.lang.Thread.run(Thread.java:479)

That's the code:

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    PrintWriter out = new PrintWriter (response.getOutputStream());
    // The servlet returns HTML.
    response.setContentType("text/html");
    out.write("props " + System.getProperties());
    try
    {
      TransformerFactory tFactory = org.apache.xalan.processor.TransformerFactoryImpl.newInstance();
      // Get the XML input document and the stylesheet.
      Source xmlSource = new StreamSource(new URL("file:c:/foo.xml").openStream());
      Source xslSource = new StreamSource(new URL("file:c:/foo.xsl").openStream());
      // Generate the transformer.
      Transformer transformer = tFactory.newTransformer(xslSource);
      // Perform the transformation, sending the output to the response.
      transformer.transform(xmlSource, new StreamResult(out));
    }
    catch (Exception e)
    {
      out.write(e.getMessage());
      e.printStackTrace(out);
    }
    out.close();
}

As I have problems in using xerces instead of xalan, I tried to refer to the implementation classes directly.

foo.xml and foo.xsl are examples of the xalan-distribution and they do exist in this directory.

I use Tomcat 3.2.1 and Apache.

Any ideas what might have gone wrong??

That's the minimalistic exapmle, think that must be O.K:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="doc">
<result>Das Ergebnis</result>
<out><xsl:value-of select="."/></out>
</xsl:template>
</xsl:stylesheet>

Thanks for your help!
