Basic KafkaProducer failing

Hello All,

I am trying to push some data into a topic using KafkaProducer API. But the
initialization is giving a NullPointer Exception.Tried debugging but could
not figure it out.

Kafka Maven version is 2.2.0

Below is the code & Exception:

> import java.util.Properties;
> import java.util.Random;
>
> import org.apache.kafka.clients.producer.KafkaProducer;
> import org.apache.kafka.clients.producer.Producer;
> import org.apache.kafka.clients.producer.ProducerRecord;
>
> public class Produce {
>
>     public static void main(String[] args) {
>         // TODO Auto-generated method stub
>         Random rand = new Random();
>
>         //put in the necessary properties to create the Kafka connection
>         Properties props = new Properties();
>         props.put("bootstrap.servers", "localhost:9092");
>         props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
>         props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
