I've updated the code in your question. Seems like your problem is related to the classpath. Take a look at this sample application which includes the java-sdk and exposes a JAX-RS class with some endpoints.
https://github.com/watson-developer-cloud/retrieve-and-rank-java
Make sure you pom is pulling all the dependencies as it seems like the java-sdk is not in the classpath even that it's in the pom.xml

I don't know if I'm going crazy, or if this is a limitation that just isn't documented (I've scoured the GCP API docs):
Is it possible to have a cloud function with a pubsub trigger on 'topic A', and inside that cloud function, publish a message to 'topic B'.
I've tried all the other triggers with identical code running (cloud functions as HTTP triggers, Cloud Storage Triggers, Firebase Triggers), and they all successfully publish to topics.
But the moment I (almost literally) copy-paste my code into a pubsub trigger, after consuming the message, when it attempts to publish it's own message to the next topic, it just hangs. The function just times-out when attempting to publish.
So to recap, is the following possible in GCP?
PubSub Topic A --> Cloud Function --> Pubsub Topic B
Thanks in advance for any clarifications! This is all in Java 11. Here's the code:
...<bunch of imports>
public class SignedURLGenerator implements BackgroundFunction<PubSubMessage> {
private static final String PROJECT_ID = System.getenv("GOOGLE_CLOUD_PROJECT");
private static final Logger logger = Logger.getLogger(SignedURLGenerator.class.getName());
/**
* Handle the incoming PubsubMessage
**/
#Override
public void accept(PubSubMessage message, Context context) throws IOException, InterruptedException {
String data = new String(Base64.getDecoder().decode(message.data));
System.out.println("The input message is: " + data.toString());
//Do a bunch of other stuff not relevant to the issue at hand...
publishSignedURL(url.toString());
}
//Here's the interesting part
public static void publishSignedURL(String message) throws IOException, InterruptedException {
String topicName = "url-ready-notifier";
String responseMessage;
Publisher publisher = null;
try {
// Create the PubsubMessage object
ByteString byteStr = ByteString.copyFrom(message, StandardCharsets.UTF_8);
PubsubMessage pubsubApiMessage = PubsubMessage.newBuilder().setData(byteStr).build();
System.out.println("Message Constructed:" + message);
//This part works fine, the message gets constructed
publisher = Publisher.newBuilder(ProjectTopicName.of(PROJECT_ID, topicName)).build();
System.out.println("Publisher Created.");
//This part also works fine, the publisher gets created
publisher.publish(pubsubApiMessage).get();
responseMessage = "Message published.";
//The code NEVER GETS HERE. The message is never published. And eventually the cloud function time's out :(
} catch (InterruptedException | ExecutionException e) {
System.out.println("Something went wrong with publishing: " + e.getMessage());
}
System.out.println("Everything wrapped up.");
}

Can you try to explicitly set the flow control param in your publisher client? like that
publisher = Publisher.newBuilder(ProjectTopicName.of(PROJECT_ID, topicName)).setBatchingSettings(BatchingSettings.newBuilder()
.setDelayThreshold(Duration.of(10, ChronoUnit.SECONDS))
.setElementCountThreshold(1L)
.setIsEnabled(true)
.build()).build();
I don't know what happens, maybe a default and global configuration of PubSub. If it's not that, I will delete this answer.
EDIT 1
Here a screen capture of the builder class on a Publisher parent classe
You have all the default value of the library. However, the behavior that you observe isn't normal. The default must stay the default even if you are in a PubSub trigger. I will open an issue and forward it to the team directly.
I created an application to read messages from Apache qpid and to send them on Apache kafka. I am using Camel with Springboot starter. My Pom looks like this -

Could you please help suggest why during autoconfiguring Springboot is not finding connectionFactory? When I debug this code, I can see connectionFactory bean is getting created. I can even see one more log line -
CamelContext has only been running for less than a second. If you intend to run Camel for a longer time then you can set the property camel.springboot.main-run-controller=true in application.properties or add spring-boot-starter-web JAR to the classpath.
however if you see my application.properties file, required property is present at the very beginning.
One more log, I can see at the beginning of application startup -
[main] trationDelegate$BeanPostProcessorChecker : Bean 'org.apache.camel.spring.boot.CamelAutoConfiguration' of type [org.apache.camel.spring.boot.CamelAutoConfiguration] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
Note - One intresting fact that exactly same code was running fine last night, just restarted my desktop and there is not even a single word changed and now it is throwing exception. Code can also be seen here - https://github.com/prashantbhardwaj/qpid-to-kafka-using-camel
I am trying to get jwk keyset from google for use with Apache Cxf OIDC and Jose Libs. The code works fine when I run it on a stand alone main method.
public class Main {
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
final WebClient client = WebClient.create("https://www.googleapis.com/oauth2/v3/certs", Arrays.asList(new JsonWebKeysProvider()), true).accept(MediaType.APPLICATION_JSON);
JsonWebKeys keys = client.get(JsonWebKeys.class);
keys.getKeys().forEach(key -> {
System.out.println("****************************************************************************");
System.out.println("ID........." + key.getKeyId());
System.out.println("Alg........" + key.getAlgorithm());
System.out.println("Key Type..." + key.getKeyType());
System.out.println("Use........" + key.getPublicKeyUse());
});
}
}
The ID, algorithm, key type and use is printed properly meaning that the keys are property populated.
Sample output:

What is causing this issue?
I realized that when Webclient is created inside tomee, it picks up bus properties provided by tomee which was causing JsonWebKeysProvider not to be invoked.
In my case below is the correct way to create the client inside tomee.
JAXRSClientFactoryBean sf = new JAXRSClientFactoryBean();
sf.setAddress("https://www.googleapis.com/oauth2/v3/certs");
sf.setProvider(new JsonWebKeysProvider());
sf.setBus(new ExtensionManagerBus());
Calling sf.setBus(new ExtensionManagerBus()); ensures tomee provided values/properties aren't picked up.
I am trying to build rest api using camel-rest-dsl. I have tried with multiple provider, spark-rest, jetty. But it throwing marshelling exception when i use RestBindingMode.json, if i remove rest binding mode it works fine.
SpringRouteBuilder
#Component
public class RestAPIRoutes extends SpringRouteBuilder {
#Override
public void configure() throws Exception {
restConfiguration().component("spark-rest")
.bindingMode(RestBindingMode.json)
.port(8787)
.dataFormatProperty("prettyPrint","true");
rest("/balance").produces("application/json").consumes("application/json")
/* mock api */
.get("/query").route().bean(BalanceService.class,"fetchBalance").endRest()
/* fetch balance by msisdn*/
.get("/query/{msisdn}").description("Fetch line balance by msisdn")
.type(BalanceInfo.class).to("bean:balanceService?method=fetchBalance(${header.msisdn})")
.post("/update").type(BalanceInfo.class).outType(BalanceInfo.class).to("bean:balanceService?method=updateBalance");
}
}
Here balanceService is a simple Spring #Service with overloaded method and BalanceInfo is simple pojo class with two field and getter setters.

Hi am facing the above exception when send data from jms queue to processor can any one help to resolve this issue.
Can any one suggest how to implement jms Queue in apache camel java RDSL.
Any pointer will be really helpful to me..
Thanks..
The message processor is a string, eg
from("test-jms:queue:test.queue").to("messageProcessor");
Which makes Camel assume its a component with that name and its not, so change it to
from("test-jms:queue:test.queue").process(new Processor() ... );
And inline a processor where you can do something with the message, or if you just want a quick test then use a log endpoint
from("test-jms:queue:test.queue").to("log:hello");
Also beware that the start method on CamelContext is not blocking. See this FAQ: http://camel.apache.org/running-camel-standalone-and-have-it-keep-running.html
