Sending Message to Azure Event Hub

I am trying to connect to Azure event hub as described here. But getting below error:

Tried looking into the answer here, but no luck.
Also, I am trying only send part mentioned in the Microsoft official docs. Is that causing the issue?
Any input in this regard would be great.

The NoSuchMethodError is a result of conflicting dependencies in which it resolved a version of project reactor that does not match the one used in azure-messaging-eventhubs. The problem is that it is resolving "reactor-core" version 3.4.1 where-as azure-messaging-eventhubs uses version 3.3.0.RELEASE. In between these releases, Flux.retryWhen's methods were changed to use Retry class rather than a function and a publisher.
You can see this dependency conflict if you execute:
.\mvnw.cmd org.apache.maven.plugins:maven-dependency-plugin:2.10:tree -Dverbose=true -Dincludes=*reactor*
One solution is to upgrade your dependency to 5.3.1.
<dependency>
<groupId>com.azure</groupId>
<artifactId>azure-messaging-eventhubs</artifactId>
<version>5.3.1</version>
</dependency>
Or, you can downgrade your version of spring-boot to one that works with reactor-core 3.3.0.RELEASE (if you want to keep using azure-messaging-eventhubs 5.0.1). Or explicitly select a version of reactor-core in your pom.xml... Though, you may encounter other NoSuchMethodErrors.

Thank you #Connie for your response.
Found that legacy event hub was used. Following this Microsoft doc helped me in connecting to the event hub.

Gobblin Error:- java.io.IOException: java.lang.ClassNotFoundException:

I'm new to the Gobblin and trying to ingest data from the Kafka to HDFS. I was able to flow the Kafka-HDFS Ingestion example successfully. But now I need to add a time-based writer partition option to my job. I did go through the TimeBasedWriterPartitioner google forum and come up with the bellow solution as suggested by Zongjun.
I create a separate Java project for my time-based writer partition class:
import gobblin.writer.partitioner.TimeBasedWriterPartitioner;
public class LogJsonWriterPartitioner extends TimeBasedWriterPartitioner<byte[]> {
public LogJsonWriterPartitioner(gobblin.configuration.State state, int numBranches, int branchId) {
super(state, numBranches, branchId);
}
#Override
public long getRecordTimestamp(byte[] payload) {
return System.currentTimeMillis();
}
}

Create a Jar from the above project and copy it to gobblin-dist/lib directory
I update gobblin-mapreduce.sh in gobblin-dist/bin directory and add the new jar name under LIBJARS.
Create a Job file as bellow:
job.name=GobblinKafkaQuickStart
job.group=GobblinKafka
job.description=Gobblin quick start job for Kafka
job.lock.enabled=false
fs.uri=file:///
kafka.brokers=localhost:9092

extract.namespace=org.apache.gobblin.extract.kafka
writer.builder.class=org.apache.gobblin.writer.SimpleDataWriterBuilder
writer.partitioner.class=com.pm.data.gobblin.kafka.LogJsonWriterPartitioner
writer.partition.granularity=day
writer.partition.pattern=YYYY-MM-dd
writer.partition.timezone=UTC
writer.file.path.type=tablename
writer.destination.type=HDFS
writer.output.format=txt

data.publisher.final.dir=/home/myuser/Desktop/Gobblin
mr.job.max.mappers=1
metrics.reporting.file.enabled=true
metrics.log.dir=${gobblin.cluster.work.dir}/metrics
metrics.reporting.file.suffix=txt
bootstrap.with.offset=earliest
Then I start gobblin as standalone using the gobblin-standalone.sh file in the bin directory.
I got below error on logs/gobblin-current.log

Whoever when I modify my job file as writer.partitioner.class=LogJsonWriterPartitioner, error is changed as java.lang.NoClassDefFoundError: gobblin/writer/partitioner/TimeBasedWriterPartitioner.
Could some help me to overcome this problem?

For the first problem, make sure that you have correct package statement for LogJsonWriterPartitioner, i would expect it to be package com.pm.data.logging.gobblin
For the second, looks like dependencies in pom.xml are not correct, and that is why TimeBasedWriterPartitioner cannot be loaded. com.linkedin.gobblin was renamed to org.apache.gobblin long time ago, and the version numbers are higher. Recent release was '0.14.0'

The line Failed to look up JNDI DataSource with name 'jdbc/spring-jdbc-test' gives me suspicions that the app runs on its own tomcat server and not the one that I have installed.
The app starts on tomcat 8.5.23 as configured in my pom (see below)

In eclipse I added a tomcat server of that version, added the sqlite jar to catalina.base/lib/ and configured the JNDI resource in catalina.base/conf/context.xml

Thanks for the help!

I just ironed out this issue in Tomcat 9. What you have looks fine, and is just missing two things from what worked for me:
a #Resource annotation in your Spring Configuration. Something like:
#Configuration
public class AppManifest {
#Resource(name = "jdbc/spring-jdbc-test", lookup = "jdbc/spring-jdbc-test") private javax.sql.DataSource springJdbcTest;
}
application.properties:
spring.datasource.jndi-name=java:comp/env/jdbc/spring-jdbc-test

Extending Mark Bramnik answer, It does look like you don't have logback, which is pretty weird because spring-boot-starter-web have a dependency on spring-boot-starter-logging. Just try to add spring-boot-starter-logging to your POM file

It looks like you're trying to use a logback logging implementation but don't have a logback jar in the classpath:
Please try adding something like this (depending on Spring Boot version there can be another actual version of logback dependency)
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.11</version>
</dependency>
Then you'll probably want to configure loggers, appenders and so forth. For more information about logging in spring boot read a chapter from official Spring Boot documentation.

Apparently I had a broken jar in the classpath, after removing everything from .m2 and updating it worked.

This worked for me, though not very intelligent: Deleted the ch folder from within .m2 folder, and did a Run > 'Maven install' from Eclipse.

Spring boot application is expecting logback classic dependency.Since its unable to find the logback-classic jar in classpath its throwing an error
Caused by: java.lang.NoClassDefFoundError: ch/qos/logback/classic/turbo/TurboFilter.
After adding the below dependency application started without any issues.
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.11</version>
</dependency>

Removing everything from maven repo and updating project in eclipse worked for me.

Deleting ch folder in .m2 directory and update maven project in eclipse project helps me in fixing this issue.

<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<!-- <version>${logback.version}</version> -->
</dependency>
Adding this logback explicitly, solved the issue in my case.

For us java.lang.ClassNotFoundException: ch.qos.logback.classic.joran.JoranConfigurator meant "I had excluded spring-boot-starter-logging but needed to add spring-boot-starter-log4j2" or something like that, apparently.
working pom:
<build>
<dependencies>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-log4j2</artifactId></dependency>
<dependency>
...something internal
<exclusions>
<exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-logging</artifactId></exclusion>
</exclusions>
According to https://docs.spring.io/spring-boot/docs/2.0.x/reference/html/howto-logging.html if you want to use log4j instead of logback you're supposed to "exclude" spring-boot-starter-logging so I guess the pattern of having to reject it from every dependency apps isn't too far off. Kind of weird though...
So maybe what happened was if you "just exclude" Maybe they were still bringing in "just logback" (without joran) as a separate dependency, which confused spring boot?

Jboss-as7 can't find oracle driver despite it being deployed

I'm using hibernate to connect to a database from a web application in jboss-as7. This is my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="HBOService">
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
<property name="hibernate.connection.url" value="jdbc:oracle:thin:#localhost:1521:XE"/>
<property name="hibernate.connection.username" value="hboweb"/>
<property name="hibernate.connection.password" value="****"/>
</properties>
I also deployed ojdb6.jar in my jboss server, as a matter of fact I can see it's listed in the Manage Deployements tab of the admin console.
Still I get this message when trying to start the application:

Is oracle.jdb.driver actually in the classpath? How can I know?

With Jboss-server the jdbc driver will be loaded from its module class loader, in your case it will scan and load class from the path
C:\Users\Developer1\Desktop\Development\Servers\jboss-as-7.1.1.Final\modules
Becaused oracle.jdb.driver is included in the jar file jdbc-oracle.jar or ojdbc6.jar so you can try to do a file search inside above module folder. If you can not find the file, you can add new module to your server according to below guide
1)Downloaded ojdbc6-11.jar and placed it inside the folder $JBOSS_HOME/modules/com/oracle/ojdbc6/main
2)Created the file module.xml under $JBOSS_HOME/modules/com/oracle/ojdbc6/main and this is the content of the file
<module xmlns="urn:jboss:module:1.0" name="com.oracle.ojdbc6">
<resources>
<resource-root path="ojdbc6.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
3) Add a dependency on the com.oracle.ojdbc6 module using a MANIFEST.MF file in the WEB-INF lib dir with contents:
Dependencies: com.oracle.ojdbc6
This can be created using the following Maven plugin configuration:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<archive>
<manifestEntries>
<Dependencies>com.oracle.ojdbc6
</Dependencies>
</manifestEntries>
</archive>
</configuration>
</plugin>
</plugins>
