client

@test     public void testp1() {      webresource clientitinerariesresource = client.resource("http://localhost:8080/tg/webresources/travelgood1/annestrandberg/itineraries");         int itineraryid = clientitinerariesresource.post(integer.class);

an error occurs in jersey when trying serialize primitive int json. same happen if use integer. use wrapper object/dto return type (see jax-rs / jersey ".get(integer.class)" , single json primitive (integer) values?)
