or you could just do (untested):

TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(stylesheet));
String s = serializeTree();
Result result = new StreamResult(response.getWriter());
transformer.transform(new SAXSource(new InputSource(new
StringReader(s))), result);

...as you don't need to use a SAXParser do you?

Also, depending on what serializeTree() does, you might not need to
serialize/reparse the input.
