I have some problems in my application, I send a POST request, but I cannot retrieve the JsonObject in my server, this is the code to send:
String quo = "{"network": {"label": "new net 111","cidr": "10.20.105.0/24"}}";
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();
JsonParser json = new JsonParser();
JsonObject jo = (JsonObject)json.parse(quo);
ClientConfig config = new ClientConfig();
Client client = ClientBuilder.newClient(config);
WebTarget target = client.target("http://localhost:7999/jersey/rest/network/"+tenant_id);
Response oj = target.request().accept(MediaType.APPLICATION_JSON)
.header("X-Auth-Token", token)
.post(Entity.json(gson.toJson(jo)));
Trying to retrieve with:
@POST
@Produces(MediaType.APPLICATION_JSON)
@Path("/{tenant_id}")
public String createNetwork(@HeaderParam(value = "X-Auth-Token") String authToken,
@PathParam(value = "tenant_id") String tenant_id,
JsonObject network){
Response response = client.target(NOVA_ENDPOINT+tenant_id)
.request(MediaType.APPLICATION_JSON)
.header("X-Auth-Token", authToken)
.post(Entity.json(gson.toJson(network)));
System.out.println("Hello");
String responseJson = response.readEntity(String.class);
JsonObject network seems to be empty, in fact it doesn't execute the method ("Hello is not printed"), the error I get is "Invalid request body" (because the JsonObject is empty I think).. What's wrong with my code?
Ok, I understood that the problem is related to Json handling such as I'm using Gson. This is my improved code (simplified version) following users suggestion, but I still have problems..

I created a GsonMessageBodyHandler.java in my package with the code suggested below by the user peeskillet. Added jersey-container-grizzly2-http.jar to my web-inf/lib (I don't know how to proper use Maven), but still doesn't work.. what am I missing?
