How set Response body in javax.ws.rs.core.Response

There is a REST API endpoint which needs to be implemented is used to get some information and send backend request to an another server and response which is coming from backend server has to set the to final response. My problem is how to set response body in javax.ws.rs.core.Response? 

@Path("analytics")
@GET
@Produces("application/json")
public Response getDeviceStats(@QueryParam("deviceType") String deviceType,
                               @QueryParam("deviceIdentifier") String deviceIdentifier,
                               @QueryParam("username") String user, @QueryParam("from") long from,
                               @QueryParam("to") long to) {

    // Trust own CA and all self-signed certs
    SSLContext sslcontext = null;
    try {
        sslcontext = SSLContexts.custom()
                .loadTrustMaterial(new File(getClientTrustStoretFilePath()), "password## Heading ##".toCharArray(),
                        new TrustSelfSignedStrategy())
                .build();
    } catch (NoSuchAlgorithmException e) {
        log.error(e);
    } catch (KeyManagementException e) {
        log.error(e);
    } catch (KeyStoreException e) {
        log.error(e);
    } catch (CertificateException e) {
        log.error(e);
    } catch (IOException e) {
        log.error(e);
    }
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
            sslcontext,
            new String[] { "TLSv1" },
            null,
            SSLConnectionSocketFactory.getDefaultHostnameVerifier());
    CloseableHttpClient httpclient = HttpClients.custom()
            .setSSLSocketFactory(sslsf)
            .build();
    HttpResponse response = null;
    try {
        HttpGet httpget = new HttpGet(URL);
        httpget.setHeader("Authorization", "Basic YWRtaW46YWRtaW4=");
        httpget.addHeader("content-type", "application/json");
        response = httpclient.execute(httpget);
        String message = EntityUtils.toString(response.getEntity(), "UTF-8");
    } catch (ClientProtocolException e) {
        log.error(e);
    } catch (IOException e) {
        log.error(e);
    } 

}

Here message is the one I need to set. But I tried several methods. Didn't work any of them.

If you want to return custom response, you can try this approach:

return Response.status(461)
            .header("Access-Control-Allow-Origin", "*")
            .entity("test")
            .type(MediaType.TEXT_PLAIN_TYPE)
            .build();

You will get response with status code 461 and custom error message "test".

One of the following solutions should do the trick:

return Response.ok(entity).build();

return Response.ok().entity(entity).build();

For more details, have a look at Response and Response.ResponseBuilder classes documentation.

Tip: In the Response.ResponseBuilder API you might find some useful methods that allow you to add information related to cache, cookies and headers to the HTTP response.
