Java Broker 0.28 HA Configuration

I working on configuring Qpid Java Broker 0.28 for high availability. The problem is that the HA server socket does not appear to be listening for connections. Qpid starts and I can send and receive messages but a second node also starts active. Using netstat to see the listening sockets does not show the HA server socket listening.

Here are the portions of the config files I think are needed:

config.json:
"virtualhosts" : [ {
"name" : "default",
"id" : "515b8d5b-e7bc-480f-b02a-b49ebc49e355",
"type" : "BDB_HA",
"configPath" : "/opt/emx/qpid/conf/virtualhosts.xml"
} ]

virtualhosts.xml:
<virtualhosts>
<virtualhost>
<name>default</name>
<default>
<store>
<class>org.apache.qpid.server.store.berkeleydb.BDBMessageStore</class>
<environment-path>/opt/emx/qpid/data/default</environment-path>
<envConfig>
<name>je.cleaner.threads</name>
<value>2</value>
</envConfig>
<envConfig>
<name>je.log.fileMax</name>
<value>5000000</value>
</envConfig>
<highAvailability>
<groupName>emx</groupName>
<nodeName>QpidNode1</nodeName>
<nodeHostPort>localhost:5001</nodeHostPort>
<helperHostPort>localhost:5001</helperHostPort>
<designatedPrimary>true</designatedPrimary>
</highAvailability>
</store>
</default>
</virtualhost>
</virtualhosts>

Any ideas what I'm missing?

Thanks, Mark
