[jdom-interest] JDOMSource and JDOMResult can produce nothing!

Use JDOMSource, but StreamResult:

public void transform(Document doc, String xslName, Writer writer)
         throws IOException, JDOMException {
     try {
         Transformer transformer = TransformerFactory.newInstance()
                 .newTransformer(new StreamSource(getXSLStream(xslName)));

         transformer.transform(new JDOMSource(doc), new
               StreamResult(writer));

     } catch (TransformerException e) {
        throw new JDOMException("XSLT Transformation failed", e);
     }
}

This is also faster, in my simple tests using JDOMSource is 30-60% faster
than using StreamSource not counting the (int his case unnessesary)
serializing time
