Manually parsing parameters from put request in tomcat

Question

I have some javascript that uses PUT requests and I'd like to be able to use request.getParameter() to read in variables. I know that Java EE does not parse stuff from PUT requests because HTML PUT was originally intended for file upload. However I am wondering if there is a way to force this behavior anyway or at a minimum how to access the parser Tomcat uses when it parses requests for POST and run it myself on the raw request string.

Thanks.

Servlets do support PUT requests through the HttpServlet#doPut. — Luiggi Mendoza

I know, and I am getting the PUT request. The problem is that it doesn't parse the form data I send. — Peter

What's the encoding of the form? multipart/form-data or application/x-www-form-urlencoded? — Paul Wostenberg

The latter: Content-Type: application/x-www-form-urlencoded; charset=UTF-8 — Peter

You should be able to retrieve the form data through HttpServlet, like mentioned by @LuiggiMendoza. Are you sure your javascript is actually sending the form data as you expect? — Paul Wostenberg

The solution appears to be to add the following attribute to the Connector element of server.xml:

parseBodyMethods="POST, PUT"

This tells Tomcat to treat PUT requests like POST requests with respect to parsing the body.
