How to Parse javax.ws.rs.core.Response

For JAX-RS 2.x Client API, use Response.readEntity(InputStream.class). Alternatively, is you don't need any specific information from the Response object, you can simple do

InputStream is = client.target(enpoint).request(
                            MediaType.APPLICATION_XML).get(InputStream.class);

Also works:

MyResponse myResponse = response.readEntity(MyResponse.class);
