Question

Anyone tried integrating CF with ActiveMQ? How was the experience? Worth spending time to build a new solution on it? I would like to learn more on how to use it, any resource you can point me to?

update: Can ActiveMQ run under JRun together with ColdFusion? We’re using the Standard Edition.

Thanks

Yes we have used ActiveMQ, in fact we have a project going on at the moment to consume data via a ColdFusion event gateway using ActiveMQ.

Note: we are running on ColdFusion 9.0.1 and we are only consuming messages.

First place to start looking is in your own ColdFusion installation which comes with an ActiveMQ example! Look in {cf_root}\gateway\docs.

So to get setup you need to:

Add the ActiveMQ jar (activemq-all-5.5.0.jar) file (available here) to the CF {cf_root}/lib directory

Move the examples.jar file in {cf_root}\gateway\lib to {cf_root}/lib

Check out the {cf_install}/gateway/docs/ActiveMQ_DeveloperGuide.pdf which will tell you how to create a configuration file. It should look something like this heartbeat.cfg example:

debug=yes
topic=yes
# the line below needs to be changed
providerURL=tcp://xxx.yyy.com:61616
initialContextFactory=org.apache.activemq.jndi.ActiveMQInitialContextFactory
connectionFactory=ConnectionFactory

# ActiveMQ requires fake JNDI entries to lookup topic names
contextProperties=topic.heartbeatTopic
topic.heartbeatTopic=com.xxx.yyy.public.heart_beat
destinationName=heartbeatTopic

Next, set up the event gateway:

• GatewayID: MyTestActiveMQGateway
• Gateway Type: ActiveMQ (this is an option on CF9)
• CFC Path: c:\foo\MyCFC.cfc (this is the CFC that will handle data incoming)
• Configuration File: c:\foo\heartbeat.cfg

Your CFC should look like so:

<cfcomponent output="false">

    <cffunction name="onIncomingMessage" access="public" output="true">
        <cfargument name="data" type="struct" />

        <cflog log="application" text="message arrived!" />


    </cffunction>

</cfcomponent>

Start your event gateway, and lo and behold you should get messages coming in, or some sort of error.

Hope that helps!
