For those who might be facing a similar problem and others who might
be interested in my previous question I have come up with an answer.
First my disclaimer: the solution below may not be the proper one but
it does work. Now on to the solution:
On the GWT Client Side:
JSONObject jObject = new JSONObject();
jObject .put("propA", new JSONString("valA"));
jObject .put(...
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST,
YOUR_PHP_URL);
builder.sendRequest(jObject.toString(), new YourReponseHandler());
Note that there is no setHeader.
On the PHP side:
Get the raw data instead of $_POST
$jsonReq = file_get_contents("php://input");
Decode the json request
$request = json_decode($jsonReq);
Cheers,
Ian
