How to get corpora in Java?

I want to get the list of corpora.
curl -X GET --header "Authorization: Bearer xxxxxxxx(about 1200 characters IAM token)" "https://https://gateway-syd.watsonplatform.net/speech-to-text/api/v1/customizations/zzzzz(customization_id)/corpora"
result(This curl command succeeds.)
{"corpora": [
{
"out_of_vocabulary_words": 0,
"total_words": 10,
"name": "corpusname",
"status": "analyzed"
},
...
but...in Java,
HttpURLConnection urlConn = null;
try {
String urlStr ="https://https://gateway-syd.watsonplatform.net/speech-to-text/api/v1/customizations/zzzzz(customization_id)/corpora";
URL url = new URL(urlStr);
urlConn = (HttpURLConnection) url.openConnection();
String token = xxxxxxxx; // about 1200 characters IAM token
urlConn.setRequestProperty("Authorization", "Bearer " + token);
urlConn.setRequestMethod("GET");
urlConn.connect();
int status = urlConn.getResponseCode();
String resMessage = urlConn.getResponseMessage();
System.out.println("## HTTPStatus:" + status + " - " + resMessage); // "## HTTPStatus:400 - Bad Request"
} catch (xxx) {
// ...
}
result(failure)
## HTTPStatus:400 - Bad Request
I used same IAM token...
Why this error occurs?
(I'm sorry that I am not good at English.)
=============added 2020/03/03
I used watson SDK(ver.6.9.2). But another error(403) occurs...
IamOptions options = new IamOptions.Builder()
.accessToken(token)
.url(urlStr) // String urlStr = https://gateway-syd.watsonplatform.net/speech-to-text/api/v1/customizations/zzzzz(customization_id)/corpora
.build();
SpeechToText speechToText = new SpeechToText(options);
System.out.println();
ListCorporaOptions listCorporaOptions = new ListCorporaOptions.Builder()
.customizationId(customizations_id) // String curstomization_id = zzzzz
.build();
List<Corpus> corpus = speechToText.listCorpora(listCorporaOptions)
.execute()
.getCorpora(); // status: 403, error: Forbidden
System.out.println(corpus.get(0));
error:

Just use the Watson Java SDK!
https://cloud.ibm.com/apidocs/speech-to-text/speech-to-text?code=java#get-a-corpus

The example that Mike pointed to won't work with version 6, which is 2 major versions back. Can you update to version 8 of the SDK? See the migration guide.
Then your authentication code would be different and the example in the API reference should work:
IamAuthenticator authenticator = new IamAuthenticator("{apikey}");
SpeechToText speechToText = new SpeechToText(authenticator);
speechToText.setServiceUrl("{url}");
replace {url} with https://api.au-syd.speech-to-text.watson.cloud.ibm.com or https://gateway-syd.watsonplatform.net/speech-to-text/api
and replace {apikey} with your key.

Unable to find a MessageBodyReader of content-type application/octet-stream

I'm struggling with an REST-Service written with JAX-RS.
I want to create and bind a client with the following code:
final String DEFAULT_RESOURCE_URL = "http://someURL:8180/";
try {
ResteasyClient client = new ResteasyClientBuilder().build().register(ClientResponseLoggingFilter.class);
ResteasyWebTarget target = client.target(DEFAULT_RESOURCE_URL).path(
"service/document/getdrawingbrowser/{documentId}/{documentType}/{partDocumentId}/{documentVersion}/{userName}");
HashMap<String, Object> keyValuesMap = new HashMap<String, Object>();
keyValuesMap.put("documentId", "xxxx");
keyValuesMap.put("documentType", "yyy");
keyValuesMap.put("partDocumentId", "000");
keyValuesMap.put("documentVersion", "000");
keyValuesMap.put("userName", "user");
Builder responseBuilder = target.resolveTemplates(keyValuesMap).request();
Response response = responseBuilder.get();
if (response.getStatus() == 200) {
byte[][] documents = response.readEntity(byte[][].class);
for (int i = 0; i < documents.length; i++) {
displayProperties(documents[i]);
}
} else {
Object entity = response.getEntity();
System.out.println(entity);
}
} catch (Throwable e) {
e.printStackTrace();
}
}
The REST-Service responds correctly I guess:
status: 200
date: Mon Sep 14 10:53:02 CEST 2015
last-modified: null
location: null
headers:
Connection :keep-alive,
Content-Disposition :attachment; filename=someFile.pdf,
Content-Type :application/octet-stream,
Date :Mon, 14 Sep 2015 08:53:02 GMT,
Server :WildFly/8,
Transfer-Encoding :chunked,
X-Powered-By :Undertow/1,
media-type: application
But in line 102 byte[][] documents = response.readEntity(byte[][].class); I'm getting an javax.ws.rs.ProcessingException which says:
javax.ws.rs.ProcessingException: Unable to find a MessageBodyReader of content-type application/octet-stream and type class [[B

I have tried several .jar files and some approaches from here and here, but sadly, none of them worked out...
Any ideas?

Try to change you Content-Type to application/pdf.

HTTP 400 Bad Request : javax.ws.rs.BadRequestException

I create a RESTful web service and write a client to use it . but when I run it i take HTTP 400 Bad Request : javax.ws.rs.BadRequestException exeption . this is my client code :
String webserviceURI = "http://localhost:8084/fsc-access";
ClientConfig clientConfig = new ClientConfig();
Client client = ClientBuilder.newClient(clientConfig);
URI serviceURI = UriBuilder.fromUri(webserviceURI).build();
WebTarget webTarget = client.target(serviceURI);
MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("plate", plate);
formData.add("startTime", start.toString());
formData.add("endTime", end.toString());
Weightings weightings = new Weightings();
weightings.getWeightings().addAll((Collection<? extends Weighting>) webTarget.path("rest").path("report").path("loadWeightingByPlate").
request().accept(MediaType.APPLICATION_XML).post(javax.ws.rs.client.Entity.form(formData), Weightings.class));
and this is my web Service :
#Path("/report")
public class WeightingRESTfulService {
#POST
#Path("/loadWeightingByPlate")
#Produces(MediaType.APPLICATION_XML)
#Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Weightings LoadWeightingInSpecTimeInSpecPlate(
#FormParam("plate") String plate,
#FormParam("startTime") String _startTime,
#FormParam("endTime") String _endTime,
#Context HttpServletRequest req) {
Long startTime = new Long(_startTime);
Long endTime = new Long(_endTime);
try {
Weightings weightings = new Weightings();
weightings.getWeightings().addAll(Weighting.LoadWeightingInSpecTimeInSpecPlate(startTime, endTime, plate));
System.out.println("no error");
return weightings;
} catch (Exception ex) {
System.out.println("Exception = " + ex);
return null;
}
}
}
can any one help me to use this web Service ?
there is some warning :

Your resource is returning an instance of Weightings, so you just need to cast it, you don't need to do the addAll()
Weightings weightings = new Weightings();
weightings.getWeightings().addAll((Collection<? extends Weighting>) webTarget.path("rest").path("report").path("loadWeightingByPlate").
request().accept(MediaType.APPLICATION_XML).post(javax.ws.rs.client.Entity.form(formData), Weightings.class));
Should be:
Weightings weightings = (Weightings) webTarget.path("rest").path("report").path("loadWeightingByPlate").
request().accept(MediaType.APPLICATION_XML).post(javax.ws.rs.client.Entity.form(formData), Weightings.class));
It won't fix your 400 exception, but you'll get a ClassCastException without it.

Why http request can take 15 sec with "GCM HTTP Connection Server "

Implementing gcm third party server, we decided to use http integration and followed google instructions.
They provide an implementation of the integration here.
We used it and sent notifications to 500 000 users using java tasks to be more effective (we need to notify our users as quick as possible).
We were surprised because http request to GCM servers could take sometimes more than 15 sec. We set log in gcm-server source and find out this issue.
Code with custom log:
public MulticastResult sendNoRetry(Message message, List<String> registrationIds) throws IOException {
if (nonNull(registrationIds).isEmpty()) {
throw new IllegalArgumentException("registrationIds cannot be empty");
}

setJsonField(jsonRequest, PARAM_DELAY_WHILE_IDLE, message.isDelayWhileIdle());
setJsonField(jsonRequest, PARAM_DRY_RUN, message.isDryRun());
jsonRequest.put(JSON_REGISTRATION_IDS, registrationIds);
Map<String, String> payload = message.getData();

log.error("Exception reading response: ", e);
}

}

We tried it from different servers, and it is not a connectivity issue.
¿Someone may know why it takes so much time for a simple http request?

Everything ok in this code... it was as simple network issue.
I believed my server had 10 Mbytes/s upload rate, and it may be true, but in fact, it is physically far from google servers so upload rate was the bottleneck.
