GWT-APACHE CXF header - gwt

Question

I have a CXF JAX-RS service and a GWT MVP4G presenter.
I call the service with the RequestBuilder and set Content-Type header to application/json.
But in the server side REST method do not call .
REST code is :
class PlayerService{
#POST
#Path("addplayer")
#Consumes({MediaType.APPLICATION_JSON})
#Produces({MediaType.APPLICATION_JSON})
String createOrSaveNewPLayerInfo(PlayerType playerType);
}
GWT code:
RequestBuilder rq = new RequestBuilder(RequestBuilder.POST, url)
rq.setHeader("Content-Type", "application/json");
rq.sendRequest(s, new RequestCallback() {
#Override
public void onResponseReceived(Request request, Response response) {
LOGGER.info(">" + response.getStatusCode() + "<");
}
#Override
public void onError(Request request, Throwable exception) {
LOGGER.info(">>" + exception.getMessage() + "<<");
}
});

I assume, that your GWT application is running on the Jetty server and your service on a Tomcat server. In this case you have two different ports: 8080 & 8888. Calling the service on 8080 will be blocked by the Same Origin Policy.
To solve this, you can switch off the policy (look for CORS). Bad idea.
Instead run your GWT application inside a Tomcat. In this case you will not have any problems with the SOP.
To set up a external server with GWT take a look here.
