Parse Input Stream into DOM object.

Last Modified: 2013-11-23
I'm attempting to create an XML DOM document from an Input Stream using the following code.  The request object if HttpServletRequest request object on a doPost call.

InputStream input = request.getInputStream();
DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = dbfac.newDocumentBuilder();
Document doc = docBuilder.parse(input);

The last line of code gets this exception:  org.xml.sax.SAXParseException: Content is not allowed in prolog.

On the post side, I've created a valid XML string that is UTF-8 encoded.  Do I need to decode first before the docBuilder.parse(input) call?  

Can anyone help me out?
