Jersey Client for Mulipart call

Question

I am using jersey client to make a REST call to an API which returns a Json and a PDF file in mulipart as the first and the second parts of the response.

final Client client = ClientBuilder.newClient();
final WebTarget target = client.target(endPoint);
final Builder request = target.request().header("Authorization", authKey);
final Response response = request.get();
final String readEntity = response.readEntity(String.class);

This returns a string response with the PDF file in byte code format. I tried to read the entity as MultiPart class and then I get an exception :

Message Body Reader Not found for media type=multipart/form-data;boundary=------#### and the getMediaType() call on client returns multipart/form-data;boundary=------####.

What is the right way to parse this multipart response using the above client?

A quick Google search gives you the result. You have to enable MultiPartFeature and you do response.readEntity(InputStream.class)

Got the below code from http://www.benchresources.net/jersey-2-x-web-service-for-uploadingdownloading-zip-file-java-client/

 // invoke service after setting necessary parameters
        clientConfig = new ClientConfig();
        clientConfig.register(MultiPartFeature.class);
        client =  ClientBuilder.newClient(clientConfig);
        client.property("accept", "application/zip");
        webTarget = client.target(httpURL);

        // invoke service
        invocationBuilder = webTarget.request();
        //          invocationBuilder.header("Authorization", "Basic " + authorization);
        response = invocationBuilder.get();

        // get response code
        responseCode = response.getStatus();
        System.out.println("Response code: " + responseCode);

        if (response.getStatus() != 200) {
            throw new RuntimeException("Failed with HTTP error code : " + responseCode);
        }

        // get response message
        responseMessageFromServer = response.getStatusInfo().getReasonPhrase();
        System.out.println("ResponseMessageFromServer: " + responseMessageFromServer);

        // read response string
        inputStream = response.readEntity(InputStream.class);
        qualifiedDownloadFilePath = DOWNLOAD_FILE_LOCATION + "MyJerseyZippedFile.zip";
        outputStream = new FileOutputStream(qualifiedDownloadFilePath);
        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, bytesRead);
        }
