Hi,
I've had some problems understanding the helloworld quickstart. There are two listeners defined:
1. a ESB-unaware JMS gateway which listens on a JMS queue 1
2. a ESB-aware listener which listens on a second JMS queue 2
The setup is quite simple, but I have difficulties regarding the flow of events. So if a JMS message is entered in queue 1 the gateway listener picks it up and transforms it into an ESB message. I guess the class JmsGatewayListener handles this. Now the message is posted to queue 2 where the ESB-aware listener is waiting and forwads the messgae to the action processing queue.
What is not clear at all is the connection between the two listeners in the configuration:
...
<services>
<service category="FirstServiceESB" name="SimpleListener" description="Hello World">
<listeners>
<jms-listener name="JmsGatewayListener" busidref="quickstartGwChannel" maxThreads="1" is-gateway="true" />
<jms-listener name="HelloWorldListener" busidref="quickstartEsbChannel" maxThreads="1" />
</listeners>
<actions>
<action name="DisplayAction" class="org.jboss.soa.esb.samples.quickstart.helloworld.MyJMSListenerAction" process="displayMessage" />
</actions>
</service>
</services>
...
How does the gateway listener knows what to do with the generated ESB message? How is the second queue referenced? Am I missing something?
Thanks!
Best regards,
Sebastian
