platform: win 2000 (possibly others)

Path of the output file, out_path, contains white spaces. transform() throws FileNotFound Exception. This behavior was not observed in b51. After changing the path to contain no white spaces, everything works fine again.

            static private String out_path =
            "C:\\Documents and Settings\\Dina\\My Documents\\ms_project\\out\\";

..... .....

            DocumentBuilder builder = factory.newDocumentBuilder();
            document = builder.parse(datafile);

            // Use a Transformer for output
            TransformerFactory tFactory = TransformerFactory.newInstance();
            StreamSource stylesource = new StreamSource(stylesheet);
            Transformer transformer = tFactory.newTransformer(stylesource);

            DOMSource source = new DOMSource(document);
            File f = new File(out_path + "\\" + datafile.getName());
            StreamResult result = new StreamResult(f);
      >>>>> transformer.transform(source, result);
