Unable to send messages from Kafka using KafkaTemplate - spring

Question

We have an existing Spring MVC application(which is SAP Hybris) wherein we want to integrate Kafka using KafkaTemplate. I have configured the kafka template in xml as below
<bean id="kafkaTemplate" class="org.springframework.kafka.core.KafkaTemplate">
<constructor-arg ref="producerFactory"/>
</bean>
<bean id="producerFactory" class="org.springframework.kafka.core.DefaultKafkaProducerFactory">
<constructor-arg>
<map>
<entry key="bootstrap.servers" value-type="java.lang.String" value="${spring.kafka.bootstrap-servers}" />
<entry key="key.serializer" value-type="java.lang.Class" value="org.apache.kafka.common.serialization.StringSerializer" />
<entry key="value.serializer" value-type="java.lang.Class" value="org.apache.kafka.common.serialization.StringSerializer" />
</map>
</constructor-arg>
</bean>
spring.kafka.bootstrap-servers is configured as localhost:9092.
Please note that, I cannot use Spring Boot or Annotation based configuration, I have to use xml based configs only
This is my sample code from controller
#RequestMapping(method = RequestMethod.GET)
public String doRegister(final Model model) throws CMSItemNotFoundException
{
String message = "Dummy Message: "+Math.random();
String topic = "Dummy_Topic";
kafkaTemplate.send(topic,message);
return "pages/register";
}
I am able to send and receive messages from command line client with my local Kafka setup, but I get below error when I am trying to send messages from my Spring MVC application.
ERROR [hybrisHTTP16] [LoggingProducerListener] Exception thrown when sending a message with key='null' and payload='Dummy Message: 0.03670242785185063' to topic Dummy_Topic:
org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 60000 ms.

I recieve no messages on command line client which is listening to that topic.

I am unable to find out why it's not working through my application but it's works fine for command line kafka producer.
Please help me in this regard.
Thanks.
