[jira] Commented: (SM-745) Allow usage of other JMS providers than ActiveMQ

    [ https://issues.apache.org/activemq/browse/SM-745?page=comments#action_37429 ] 
            
Guillaume Nodet commented on SM-745:
------------------------------------

The main problem will come from the discovery mechanism.
Currently, the jms / jca flow uses the ActiveMQ feature called "Advisory Topics".
See http://www.activemq.org/site/advisory-message.html

This feature is used so that a new node in the cluster will be detected by receiving
a message in onAdvisoryMessage method.  This one will send messages to
broadcast its internal activated endpoints.  This will need to be rewritten to use
standard topics.

> JMSFlow and JCA flow are too tightly bound to ActiveMQ. Instead of ActiveMQ specific classes jms Interfaces should be used where possible.
> I have attached a patch that replaces ActiveMQConnection and ActiveMQConnectionFactory by the jms equivalents.
> There is one possible issue with my patch.  The getConnectionFactory now returns a ConnectionFactory instead of a ActiveMQConnectionFactory. I donĀ“t know if any other part of the sources depends on the specific class.
> My patch is of course only the first step. The next could be having a specific subclass JMSFlowActiveMQ that does all stuff that is ActiveMQ specific.
> I will deliver a second patch for this.
