ActiveMQ Brokers using HTTP to communicate

G'day.

I have ActiveMQ 5.1 working just fine using autodiscovery and multicast.

I would like to configure 2 ActiveMQ 5.1 brokers to talk to each other using
HTTP port 80, to make it easy with regards to firewalls. I assume this is
possible, I see talk about client -> Broker using HTTP and have seen posts
on Broker -> Broker using HTTP, but no concrete 'howto', that I have found,
so far.

At this time, each ActiveMQ is running on it's own server, with no other
http server, so port 80 is ok for ActiveMQ to use, although, I would like to
know if I can integrate ActiveMQ into an existing HTTP server (httpd) such
that they communicate with each other via a more complete url, rather than
simply address:port using http.

I figured if I edited activemq.xml and commented out
<networkConnector name="default-nc" uri="multicast://default"/>
and replaced it with something like
<networkConnector name="Broker1 and Broker2"
uri="static://(http://192.168.0.5:80,http://192.168.1.5:80)"/>
I might get some joy, but I keep receiving a connection refused.

WARN DiscoveryNetworkConnector - Could not start network bridge
between: vm://this-one and: http://192.168.1.5:80 due to:
java.net.ConnectException: Connection refused: connect

Is there some other step I should be doing? Maybe a jar from the
lib/optional directory needs to be moved up into the lib directory?

Thanks, in advance.

...Lyall

Excellent.
I have the two brokers talking using http using the configuration settings,
shown below.
I have disabled multicast as I only want the two to communicate using port
80.
Thank you.

        <transportConnectors>
            <transportConnector name="openwire" uri="tcp://localhost:61616"
/>
           <!--  <transportConnector name="openwire"
uri="tcp://localhost:61616" discoveryUri="multicast://default"/> -->
            <transportConnector name="http" uri="http://0.0.0.0:80"/>
            <transportConnector name="ssl" uri="ssl://localhost:61617"/>
            <transportConnector name="stomp" uri="stomp://localhost:61613"/>
            <transportConnector name="xmpp" uri="xmpp://localhost:61222"/>
        </transportConnectors>

        <networkConnectors>
            <!-- by default just auto discover the other brokers -->
            <!-- !! <networkConnector name="default-nc"
uri="multicast://default"/> -->
            <!-- Example of a static configuration: -->
            <networkConnector name="Host1 and Host2" 
			       uri="static://(http://192.168.1.1:80,http://192.168.1.2:80)"/>
        </networkConnectors>

Hi,

you need to start transport connectors as well.

Take a look at these configurations used in a test case for example

http://fisheye6.atlassian.com/browse/activemq/trunk/activemq-core/src/test/resources/org/apache/activemq/usecases/sender-http.xml?r=HEAD
http://fisheye6.atlassian.com/browse/activemq/trunk/activemq-core/src/test/resources/org/apache/activemq/usecases/receiver-http.xml?r=HEAD

Cheers
