Get Posted XML from HttpServletRequest Object

Question

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 ge

Answer 1

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).
