VMware vCenter API exception:The request refers to an unexpected or unknown type?

The console shows exception:"The request refers to an unexpected or unknown type" when I create a cluster.please help me. code shows the following:
vimPort.login(serviceContent.getSessionManager(),
userName, password, null);
ManagedObjectReference data = getDatacenterByName2("Datacenter");
String name = "cluster_hi";
ClusterConfigSpec spec = new ClusterConfigSpec();
ClusterDasConfigInfo value = new ClusterDasConfigInfo();
value.setAdmissionControlEnabled(true);
value.setEnabled(true);
spec.setDasConfig(value);
vimPort.createCluster(data, name, spec);

Spring cloud kafka and avro serialization issue

I use spring-cloud-stream-schema to read avro messages from kafka. I configured input channel in MessagesChannels:
#Input("topicName1")
SubscribableChannel fromInput1();
I have configuration file like that:
#Configuration
#EnableBinding(MessagesChannels.class)
#EnableSchemaRegistryClient
public class MessageConfiguration {
#Bean
public MessageConverter topic1MessageConverter() throws IOException {
return new AvroSchemaMessageConverter(MimeType.valueOf("avro/bytes"));
}
}
And my consumer is called with
fromInput1().subscribe(this::onMessage);
void onMessage(Message message) {
}
When I actually sent message I got this error:
nested exception is java.lang.ClassCastException:
org.apache.avro.generic.GenericData$Record cannot be cast to [B
Actually raw bytes are parsed correctly into org.apache.avro.generic.GenericData$Record. But spring requires Message class. How to cast GenericData$Record to Message or how to cast GenericData$Record directly to generated by avro-tools class?
More details:
2017-03-06 11:23:10.695 ERROR 19690 --- [afka-listener-1] o.s.kafka.listener.LoggingErrorHandler : Error while processing: ConsumerRecord(topic = topic1, partition = 0, offset = 7979, CreateTime = 1488784987569, checksum = 623709057, serialized key size = -1, serialized value size = 36, key = null, value = {"foor": "bar"})

I think you need to set the contentType for the incoming message channel to use application/*+avro as specified here

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:

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.

Promise timeouts and WS.get Timeout in PlayFramework 2.1 JAVA

I am trying to access to an URL using WS on Play Framework 2.1 using JAVA api.
Here is what I want:
Some where in the code, start a WS request using WS.get() (I set timeout 1000ms)
If WS.get times out or another exception happens, I don't want my Promise throw an exception (since my flow reqiures it that way) So I use Promise.recover() to wrap that promise with another. Which returns a null Reponse object in case of failures.
Some where else in code I want to "get" my Response. I wait for 5000ms but what I get is java.util.concurrent.TimeoutException: Futures timed out after [5000 milliseconds]
How? WS.get() timesout after 1000ms and since it throws an java.util.concurrent.TimeoutException: No response received after 1000 it is catched by my recover function. It returns a null response instead of an exception.
So promise is "completed" after 1000ms at most. Why it times out and throws an exception after 5000 ms?
Code:
Logger.info("Fetch started: " + new Date().toString());
Promise<WS.Response> p1 = WS.url("http://athena.ics.forth.gr:9090/RDF/VRP/Examples/tap.rdf").setTimeout(1000).get();
Promise<WS.Response> p2 = p1.recover(new Function<Throwable, WS.Response>() {
#Override
public Response apply(Throwable a) throws Throwable {
Logger.error("Promise thrown an exception so I will return null. " + new Date().toString() + " " + System.currentTimeMillis(), a);
return null;
}
});
try {
/* This should return null or valid response but shouldn't throw an exception */
Response r = p2.get(5000L);
Logger.info(r.toString());
} catch (Exception e) {
/* Sholdn't happen! */
Logger.error("Outer exception: " + " " + System.currentTimeMillis(), e);
}
Logger.error("Fetch finished: " + new Date().toString() + " " + System.currentTimeMillis());
Output I get:
[info] application - Fetch started: Tue Mar 19 10:04:42 EET 2013
[error] application - Outer exception: 1363680287626
java.util.concurrent.TimeoutException: Futures timed out after [5000 milliseconds]

Even I wait for promise2 and promise2 is "recover wrapped promise1" recover function runs AFTER exception is thrown.

grizzly2 jersey REST app returns 404 on first request, then success on all others

I have a very simple Java REST app that uses grizzly2 (jersey-grizzly2 1.12) and jersey (jersey-bundle 1.12)
When I make my first http request, I get a 404 response (but the mapped method still executes on the server). If I make the identical request again, then I get the expected 200 response.
The crazy part is, that even for the 404 error, the mapped method still executes.
Perhaps there is a bug? Or I've misconfigured my server? This is the first time i've tried grizzly2, so any insight is welcome!
I start the server like this:
final ResourceConfig rc = new DefaultResourceConfig(
TestResource.class
);
rc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
rc.getFeatures().put(ResourceConfig.FEATURE_TRACE, true);
URI path = UriBuilder.fromPath(baseUri).build();
HttpServer httpServer = GrizzlyServerFactory.createHttpServer(path, rc);
httpServer.start();
And my resource looks like this:
#Path("/test")
public class TestResource {
#GET
#Produces(MediaType.APPLICATION_JSON)
#Path("go")
public Integer startSomethingElse() {
return new Integer(4);
}
}
And my sample connection examples:
