Multiple brokers aren't a requirement. Do appA/appB need to share destinations
with appC? If not, then multiple brokers using default configuration (avoiding
port conflicts of course) will work fine. If you do need to share JMS
destinations, you'd need either a single broker or a broker network.
For a single broker (e.g. running in Geronimo1), you'd need to configure your
JMS resources in Geronimo2 to use TCP (VM transport won't work. You could use
multicast or discovery protocol). Something like:
<resourceadapter-instance>
<resourceadapter-name>arcgis-jms</resourceadapter-name>
<config-property-setting
name="ServerUrl">tcp://localhost:61616</config-property-setting>
<nam:workmanager xmlns:nam="http://geronimo.apache.org/xml/ns/naming-1.2";>
<nam:gbean-link>DefaultWorkManager</nam:gbean-link>
</nam:workmanager>
</resourceadapter-instance>
A broker network would require G 2.2 (it would be very difficult/impossible to
configure a broker network on G 2.1.x). In var/activemq/conf/activemq.xml add:
<networkConnectors>
<networkConnector
uri="static://(tcp://localhost:61616,tcp://localhost:61626)" dynamicOnly="true"
networkTTL="5"/>
</networkConnectors>

In a broker network, VM transport is possible between client and broker. VM
transport would not work between brokers.

AMQ has examples. I don't think we have any examples set up in Geronimo.
