API on frodo HTTP/1.1 415 Unsupported Media Type

Hi,
Just updated from Eden to Frodo and it looks like CURL commands doesnt work anymore and the API had important schema change that i cant find on the wiki
Basicly im getting
HTTP/1.1 415 Unsupported Media Type
for every call for example
curl -i -X POST -d '{"jsonrpc":"2.0", "method":"Application.Quit"}' http://xbmc:www@localhost:8080/jsonrpc
curl -i -X POST -d '{ "jsonrpc": "2.0", "method": "Player.Open", "params": { "item": { "file": "dvd://dev/dvd" } }, "id": 1 }' http://xbmc:www@localhost:8080/jsonrpc

HTTP/1.1 415 Unsupported Media Type
Content-Length: 0

Thanks,

As mentioned many times already and as also explained in the "Frodo API changes" article on the wiki (see http://wiki.xbmc.org/index.php?title=Fro...#HTTP_POST ) you need to specify the
header in your HTTP request. There are also some examples in the forum that contain the syntax on how to do this with CURL.

Thanks,
The -H over looked it on the wiki.
