Clustering a JMS Topic

Question

I'm trying to create a distributed JMS topic using the wlconfig ant task (MBean).
I can create a topic on a single server fine, but I can't figure out how to create a distributed topic that I could access on any server in the cluster.
This is what I have so far, which seems to run, but I can't lookup the topic under the JNDI name in the server,
<wlconfig url="t3://${JEE_HOST}:7001/" username="${JEE_USER}" password="${JEE_PASSWORD}">
<query domain="mydomain" type="Cluster" name="*" property="cluster"/>
<query domain="mydomain" type="Server" name="server1" property="server1"/>
<query domain="mydomain" type="Server" name="server2" property="server2"/>
<query domain="mydomain" type="Server" name="server3" property="server3"/>
<create type="JMSConnectionFactory" name="EmployeeTopicConnectionFactory">
<set attribute="JNDIName" value="jms/EmployeeTopicConnectionFactory"/>
<set attribute="XAServerEnabled" value="false"/>
<set attribute="Targets" value="${cluster}"/>
</create>
<create type="JMSServer" name="EmployeeJMSServer1">
<set attribute="Targets" value="${server1}"/>
</create>
<create type="JMSServer" name="EmployeeJMSServer2">
<set attribute="Targets" value="${server2}"/>
</create>
<create type="JMSServer" name="EmployeeJMSServer3">
<set attribute="Targets" value="${server3}"/>
</create>
<create type="JMSDistributedTopic" name="EmployeeTopic">
<set attribute="JNDIName" value="jms/EmployeeTopic"/>
<set attribute="LoadBalancingPolicy" value="Random"/>
<set attribute="Targets" value="${cluster}"/>
</create>
</wlconfig>
This produces the following in the config.xml
<jms-server>
<name>EmployeeJMSServer1</name>
<target>server1</target>
</jms-server>
<jms-server>
<name>EmployeeJMSServer2</name>
<target>server2</target>
</jms-server>
<jms-server>
<name>EmployeeJMSServer3</name>
<target>server3</target>
</jms-server>
<migratable-target>
<name>server1 (migratable)</name>
<notes>This is a system generated default migratable target for a server. Do not delete manually.</notes>
<user-preferred-server>server1</user-preferred-server>
<cluster>employee-cluster</cluster>
</migratable-target>
<migratable-target>
<name>server2 (migratable)</name>
<notes>This is a system generated default migratable target for a server. Do not delete manually.</notes>
<user-preferred-server>server2</user-preferred-server>
<cluster>employee-cluster</cluster>
</migratable-target>
<migratable-target>
<name>server3 (migratable)</name>
<notes>This is a system generated default migratable target for a server. Do not delete manually.</notes>
<user-preferred-server>server3</user-preferred-server>
<cluster>employee-cluster</cluster>
</migratable-target>
<jms-interop-module>
<name>interop-jms</name>
<sub-deployment>
<name>EmployeeTopicConnectionFactory</name>
<target>employee-cluster</target>
</sub-deployment>
<sub-deployment>
<name>EmployeeTopic</name>
<target>employee-cluster</target>
</sub-deployment>
<descriptor-file-name>jms/interop-jms.xml</descriptor-file-name>
</jms-interop-module>
and the jms interop xml
<connection-factory name="EmployeeTopicConnectionFactory">
<jndi-name>jms/EmployeeTopicConnectionFactory</jndi-name>
<transaction-params>
<xa-connection-factory-enabled>false</xa-connection-factory-enabled>
</transaction-params>
</connection-factory>
<distributed-topic name="EmployeeTopic">
<jndi-name>jms/EmployeeTopic</jndi-name>
<load-balancing-policy>Random</load-balancing-policy>
</distributed-topic>
