[Spadow]

I am in need to create xml as a string to pass to server. I have managed to convert the data into xml but the encoding format set to utf-8 as default. What i need is i want to set it as utf-16 format. But i haven't got any idea of setting it.\[code\] private void XmlCreation(int size,List<DataItem> item) throws ParserConfigurationException, TransformerException { DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder(); Document document = documentBuilder.newDocument(); Element rootElement = document.createElement("ArrayOfDataItem"); document.appendChild(rootElement); for (DataItem in: item) { Element subroot = document.createElement("DataItem"); rootElement.appendChild(subroot); Element em = document.createElement(in.getKey()); em.appendChild(document.createTextNode(in.getValue())); subroot.appendChild(em); } TransformerFactory transformerFactory = TransformerFactory.newInstance(); Transformer transformer = transformerFactory.newTransformer(); java.io.StringWriter sw = new java.io.StringWriter(); DOMSource source = new DOMSource(document); StreamResult result = new StreamResult(System.out); transformer.transform(source, result); String xml = sw.toString(); System.out.println(xml); }}\[/code\]Thanks guys
