Question

I’ve been working on a webservice that prints the content of a table as XML – I used a WebRowSet to do this.

response.setContentType("text/xml");
WebRowSet webRowSet = new WebRowSetImpl();
webRowSet.writeXml(resultSet, response.getWriter());

(HttpServletResponse response)

While this much works fine, I simply can’t figure out howto apply a Stylesheet to the XML. I tried to use a transformer to do this.

webRowSet.writeXml(resultSet, OutputStream);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer(new StreamSource("file.xsl"));
transformer.transform(new StreamSource(InputStream), 
                      new StreamResult(response.getWriter()));

I fail to understand what the OutputStream in writeXml and the InputStream in the StreamSource would be. (I don’t want to save the data in a file)

I’ve found a question that might be related?

An explanation of how I could solve this problem would be very appreciated.

Answer 1

You could have the webRowSet write its XML to a ByteArrayOutputStream (preferably wrapped inside a BufferedOutputStream for buffering purposes).

Next, you can instruct your Transformer to read from a ByteArrayInputStream, which you instantiate with the byte[] you obtain from the ByteArrayOutputStream.
