To configure multiple publishers on the same machine use the service-config.xml file.
Update the port value only when there are multiple publishers on the same machine. If the publishers are running on separate machines, you need not update this value in the service-config.xml file.
The service-config.xml file is in ComponentName/ua/services/RMI/service-config.xml
To configure multiple publishers on the same machine, specify the administration port of the publisher:
<set-property property="port" value="portvalue" />
