I managed to partially get a network of brokers working. This is what I
learnt in the process.
1. All brokers in the network should use a different name.
2. "Transport Connector" is what clients and peer brokers communicate
with a broker using. So if you have a transport connector like
<transportConnector name="openwire" uri="tcp://localhost:61616"/>
the broker can talk on tcp://localhost:61616
3. "Network Connector" is what the broker uses to connect other
brokers. So if you have <networkConnector name="host1 and
host2" uri="static://(tcp://host1:61616,tcp://host2:61616)"/> then
the broker will try to connect to other brokers running with
transport connectors tcp://host1:61616 and tcp://host2:61616
Still trying to figure out how to get failover going .... the clients
don't switch over to other brokers but just exit.

Hi Naga,
Do you have different names for the brokers ... or do you use the
same name?
I've been using the same name.
