I'm trying to integrate Spring Boot (2.6.3) with Camel (3.14.0) to send a simple query to ElasticSearch.
The project is located at https://github.com/saavedrah/springboot-camel-elastic
I have a timer that sends a ElasticSearch query every 60 sec.
However, the following exception is generated:
2022-01-26 11:08:48.036 WARN 23668 --- [1 - timer://foo] o.a.camel.component.timer.TimerConsumer : Error processing exchange. Exchange[2578AAA06ED30CB-0000000000000000]. Caused by: [org.apache.camel.CamelExecutionException - Exception occurred during execution on the exchange: Exchange[]]

UPDATE 1
Accordingly with this site CAMEL-17183 the downloaded version of ElasticSearch (7.15.2) does not have the [org.elasticsearch.common.CheckedConsumer] class.
So, how should I update the gradle.properties to get the supported version of ElasticSearch(7.8.0) ?
UPDATE 2
Gradle properties was updated to force the version of ElasticSearch.
configurations.all {
resolutionStrategy {
dependencySubstitution {
substitute module('org.elasticsearch.client:elasticsearch-rest-high-level-client') with module('org.elasticsearch.client:elasticsearch-rest-high-level-client:7.8.0')
substitute module('org.elasticsearch.client:elasticsearch-rest-client') with module('org.elasticsearch.client:elasticsearch-rest-client:7.8.0')
substitute module('org.elasticsearch:elasticsearch') with module('org.elasticsearch:elasticsearch:7.8.0')
}
}
}
And now I'm getting the following exception, I guess it is related with the lack of parameters passed to the query...

Any help is appreciated.
What Huang was telling me was that I should put some query in my timer component body to pass it to the Search operation, something like:
from("timer://foo?fixedRate=true&period=60000")
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
exchange.getIn().setBody("{\"query\":{\"match_all\":{}}}");
}
})
.to("direct:search");
from("direct:search")
.to("elasticsearch-rest://elasticsearch?operation=Search&indexName=twitter");
Thank you.
I'm following https://quarkus.io/guides/security-openid-connect#integration-testing-wiremock to create some tests for my Quarkus app:
#QuarkusTest
#TestHTTPEndpoint(BannerApi.class)
#QuarkusTestResource(OidcWiremockTestResource.class)
public class BannerApiTest {
#Test
public void testListUnauthenticated() {
when().get().then().statusCode(401);
}
}
I followed the setup as-is, except I created application.properties in src/test/resources with the following contents:
quarkus.oidc.auth-server-url=${keycloak.url}/realms/quarkus/
quarkus.oidc.client-id=quarkus-service-app
quarkus.oidc.application-type=service
smallrye.jwt.sign.key.location=privateKey.jwk

Where do I miss? I'm using Quarkus 2.1.0.
When trying to run a flume job I am getting the error given below. I am running this on a cloudera setup.
Kafka is the source
Morphline is used as an interceptor with avro records getting created from it.

I was able to locate the relevant code on flume:
https://github.com/apache/flume/blob/trunk/flume-ng-sinks/flume-hdfs-sink/src/main/java/org/apache/flume/sink/hdfs/BucketWriter.java (line:602)
// write the event
try {
sinkCounter.incrementEventDrainAttemptCount();
callWithTimeout(new CallRunner<Void>() {
#Override
public Void call() throws Exception {
writer.append(event); // could block
return null;
}
});
} catch (IOException e) {
LOG.warn("Caught IOException writing to HDFSWriter ({}). Closing file (" +
bucketPath + ") and rethrowing exception.",
e.getMessage());
close(true);
throw e;
}
Error: Caught IOException writing to HDFSWriter (no protocol: value). Closing file
I am not able to workout what the error no protocol: value means.
I am unable to find any reference to this error in any context related to Flume and HDFS.
Incerceptor protocol was missing from the configuration -- Added "file:/" in the flume configuration file which that fixed the issue.
Similar issue reference : https://community.cloudera.com/t5/Data-Ingestion-Integration/Flume-HDFS-sink-error-quot-unknown-protocol-hdfs-quot/td-p/19344
This code fails when used by a local java client to lookup a JMS ConnectionFactory from a Glassfish server running on localhost.
Can anyone tell me why? I'm so desperate even useful insults are welcome.
I put the Console output below (as formatted by my program).

ctx = new InitialContext(env);

I came to know that glassfish 4.1 is having this bug where local client cant connect to the MDB deployed on server. I tried the same with two ejb projects and it is working just fine.
I'm running JBoss 5.1 GA with JDK 1.6 on Linux and trying to call session bean(jar containing this session bean is deployed on jboss server), Now i want to call this session bean from client, but didnt work.
Java Code at client Side

After seeing above error i added jboss-logging-spi.jar in the classpath of 'CallingJbossSessionBeanFromClient' class and got following error

Plz tell me, am i on the right way to call sesion bean from client java class?
I have spent hours looking for solution on Google. However I cannot seem to find anything that holds the hand..try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic
Plz suggest solution
The solution to this problem is to open the JMX-Console and click on the service=Naming to view the MBean view of the Naming service. Check if the port used is still 1099.....
Changed the URL to jnp://182.158.93.41:1299, the client could communicate with the EJB.
If you are running over JBoss AS 5.x
Here is RMI based JNDI description.
RMI-Port: default -1099 / If dynamic port changed to ports-01 Then Port is 1199
Now, Remaining Things are OK, Modify code ass below
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://182.158.93.41:1199");
Another Point is case of accessing
SlsSessiongRemote remote=(SlsSessionRemote) context.lookup("SlsSessionBean/remote");
if - #Stateless(name="SlsSessionBean")
Then Remote JNDI- [SlsSessionBean/remote] and Local JNDI - [SlsSessionBean/local]
if - #Stateless(name="SlsSessionBean", mappedName="SlsSessionBeanGlobal")
Then Remote JNDI- [SlsSessionBeanGlobal] and Local JNDI - [SlsSessionBean/local]
