Is "internal" queue required for messaging routing?

[heyyou]

Looking over the quickstarts, I see that for the <providers>, there are usually two queues defined, an inbound queue and

an internal queue:

            <jms-bus busid="inbound">

                <jms-message-filter dest-type="QUEUE" dest-name="IN" />

              </jms-bus>

              <jms-bus busid="internal">

                  <jms-message-filter dest-type="QUEUE" dest-name="queue/INTERNAL" />

              </jms-bus>

then in the <services> two listeners are defined for the inbound and internal queues.

         <listeners>

                <jms-listener name="JMS-Gateway"   busidref="inbound" is-gateway="true" />

                <jms-listener name="JMSpassthru"  busidref="internal"/>

            </listeners>

If I'm routing to another JMS queue, I've created an action that sends the message yet to another outbound

queue.

What is the purpose of this "internal" queue used in the quickstarts and is it required?

I've tried removing it but it seems to cause other issues ..

Thanks

Check out section 5.3 of the Getting Started guide, it has a good explanation of the difference between ESB aware and unaware messages.

Thank you Tom for the response.

Looks you can choose between using

      invmscope="GLOBAL"

or

  ...

  <jms-bus busid="internal"><jms-message-filter dest-type="QUEUE" dest-name="queue/INTERNAL" /></jms-bus>

   ...

   <jms-listener name="JMSpassthru"  busidref="internal"/>

Depending on the needs.
