How do I make a servlet accept XML in http?

Question

Not sure if this is the right forum for this but here goes...
If I understand httpservlets properly they rely on a URL on the server being used to be 'activated'.
How do I set up a servlet to handle any http that is sent to a certain port on a server?
Once in the servlet I want to extract the XML from the http message etc and then return an XML response. This I think I can cope with (famous last words).
All the httpservlet examples I can find are based around HTML, but I'm guessing that some of you XML users out there are doing this!
I'm using NetBeans 5 and Sun App server.

Okay, let's assume you know something about servlets.
How do I set up a servlet to handle any http that is sent to a certain port on a server?You don't. Your application server handles HTTP requests to that port. Based on the URL, it may delegate those requests to a servlet in a web application. You have to configure the application so that each servlet gets the right requests.
Once in the servlet I want to extract the XML from the http message etcPerhaps you're going to send the XML as a parameter using the POST method. If that's the case then it's readily available as an ordinary request parameter. Or if you're using a multipart request, you can treat it like a file upload as dmbdmb said.
and then return an XML responseThen by all means write XML to the response. It's just text, after all. You may need to use "text/xml" as your content type.
