Do you get the same 415 error when you go to /connection in your browser? (If so, then the problem is in your ServiceConnection class, rather then in your Android code).
Also, in my Android code, I don't wrap the resource, but do the call directly on the ClientResource class, as in: Engine.getInstance().getRegisteredConverters().add(0, new JacksonConverter()); ClientResource commitsClient = new ClientResource(BASE_URL + "commitments/"); commitsClient.setEntityBuffering(true); Representation rep = commitsClient.post(commitDTO); Good luck!
