 final HttpClient httpClient = new DefaultHttpClient.Builder();

 final SomePOJORequest postPojo = new MyPOJO("id", "data");
 final Response<SomePOJOResponse> postResponse = httpClient.post("http://localhost/pojo",
                                                                 postPojo,

 final Response<SomePOJOResponse> getResponse = httpClient.get("http://localhost/pojo/id",
                                                                 SomePOJOResponse.class);

 final SomePOJORequest putPojo = new MyPOJO("updated-data");
 final Response<SomePOJOResponse> postResponse = httpClient.post("http://localhost/pojo/id",
                                                                 putPojo,
