hazelcast client iTopic doesn't see the topic - hazelcast

Question

I have the following code on the hazelcast instance:
ITopic<String> topic;
HazelcastInstance hz = Hazelcast.newHazelcastInstance();
topic = hz.getTopic("data");
Data is repeatedly published to the topic
String event = "abc123"
topic.publish(event);
then on another machine on the LAN I run the client like this:
public class Listener implements MessageListener<String>
{
ClientConfig clientConfig = new ClientConfig();
clientConfig.getNetworkConfig().addAddress("192.168.21.89:5701");
HazelcastInstance client = HazelcastClient.newHazelcastClient(clientConfig);
ITopic<String> topic = client.getTopic("data");
topic.addMessageListener(new Listener());
public void onMessage(Message<String> m) {
System.out.println("onMessage");
}
}
The client finds the hz node and starts, but doesn't see any data message on the iTopic. I thought hz instances and clients would autodiscover each other in default? Do I have to configure hz for the network somehow?
The client log shows:
2015-09-01 15:43:05,518 INFO Listener [main] In main()

Answer 1

This was my own problem because I was not actually publishing the data I wanted to listen to. Aaargh!
