Making POST requests with parameters in GWT

Question

I am trying to do a POST request with a set of parameters to a given URL. The problem I am having is that the POST request is made, but no parameters are passed.

Answer 1

A web form can't be used to send a request to a page that uses a mix of GET and POST. If you set the form's method to GET, all the parameters are in the query string. If you set the form's method to POST, all the parameters are in the request body.
