Hello Sherif,
I've tried with your sample code, and it works for me.
I've just changed this piece of code, in the "represent" method:
MediaType mediaType = variant.getMediaType();
if (MediaType.APPLICATION_JSON.equals(mediaType))
I send you my sample code, that, I've tested it with Restlet 1.1 and
Restlet 1.2 (current trunk in both cases) .
Best regards,
Thierry Boileau
