not able see messages published from Kafka producer(Spring Integration) - spring-integration

Question

Im using Spring Integration in Java Rest api to produce messages into Kafka..
https://github.com/spring-projects/spring-integration-kafka
when i say
kafkaMessageChannel.send(MessageBuilder.withPayload("hi kafka from rest api").build());
this returns true that means its publishing ..but not able to see the messages in the topic logs..
i checked the logs under /usr/local/var/lib/kafka-logs/test-0
even i ran the consumer console but im not able to see the messages published from api..
kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning
but if i produce messages from producer console im able to see messages in the topic logs as well as consumer console..
kafka-console-producer.sh --broker-list localhost:9092 --topic test
im using same brokerlist and topic name in spring integrated rest api..
my spring config outbound xml..

</beans>
And the listener implementation..
public class ProducerListnerKafka extends LoggingProducerListener{
#Override
public void setIncludeContents(boolean includeContents) {
super.setIncludeContents(true);
}
#Override
public void onError(String topic, Integer partition, Object key, Object payload, Exception exception) {
super.onError(topic, partition, key, payload, exception);
}
#Override
public void onSuccess(String topic, Integer partition, Object key, Object value, RecordMetadata recordMetadata) {
String kafkatopic=recordMetadata.topic();
}
}
i tried debugging its not even coming to onError function.
