Get Posted XML from HttpServletRequest Object

I have a Filter that receives the HttpServletRequest and the request is a POST that consists of an xml that I need to read into my filter method. What is the best way to get the posted xml from the HttpServletRequest object.

That depends on how the client has sent it.

If it's been sent as the raw request body, then use ServletRequest#getInputStream():

InputStream xml = request.getInputStream();
// ...

If it's been sent as a regular application/x-www-form-urlencoded request parameter, then use ServletRequest#getParameter():

String xml = request.getParameter("somename");
// ...

If it's been sent as an uploaded file in flavor of a multipart/form-data part, then use HttpServletRequest#getPart().

InputStream xml = request.getPart("somename").getInputStream();
// ...

That were the ways supported by the standard servlet API. Other ways may require a different or 3rd party API (e.g. SOAP).
