HttpServletRequest - Get query string parameters, no form data

Question

In HttpServletRequest, getParameterMap returns a Map of all query string parameters and post data parameters.

Is there a way to get a Map of ONLY query

Answer 1

Contrary to what cularis said there can be both in the parameter map.

The best way I see is to proxy the parameterMap and for each parameter retrieval check if queryString contains "&?=".

Note that parameterName needs to be URL encoded before this check can be made, as Qerub pointed out.

That saves you the parsing and still gives you only URL parameters.
