JSP runs twice for 1 request.

Question

Can anyone explain why after a single request to this page there is two hashes on the commandline? This is running on Java 1.5 with Tomcat 5 and using Apache xerces and xalan.
<%@ page
    language="Java"
    import="java.io.*, java.util.*, javax.xml.transform.*,
javax.xml.transform.stream.*"
%>
<%
   File xml = new File(this.getServletContext().getRealPath(""), "menu.xml");
   File xsl = new File(this.getServletContext().getRealPath(""), "menu.xsl");
   TransformerFactory factory = TransformerFactory.newInstance();
    StreamSource stylesheet = new StreamSource(xsl.toString());
    Transformer transformer = factory.newTransformer(stylesheet);
    StreamSource source = new StreamSource(xml.toString());
    StreamResult result =
        new StreamResult(out);
    transformer.transform(source, result);
    System.out.println("#");
%>

Answer 1

Simple browser call to the jsp page using Mozilla Firefox. I haven't actually tried Internet Explorer or another browser yet.
I have tried writing the xml output to a StringWriter instead of the JSPWriter named out and this seems to make the page run only 1, but as soon as I write out the HTML rendered from the XML it runs twice.
This is very perplexing...
