Re: Mule closes down when the ActiveMQ server is shut down.

Hi,

I am also facing the same problem with Mule 2.0.2. If ActiveMQ is not up and running, I cannot start my Mule server and if I close the ActiveMQ server in between then Mule server goes down and throws exception.

Configuration file -

<spring:beans>
   
    <!-- Retry Connection Strategy for when we can't reach the topic -->
    <spring:bean name="SimpleRetryConnectionStrategy"
                 class="org.mule.transport.SimpleRetryConnectionStrategy">
      <spring:property name="retryCount" value="20" />
      <spring:property name="retryFrequency" value="5000" />
      <spring:property name="doThreading" value="false" />
    </spring:bean>
       
    </spring:beans>

Thanks,
Manupriya



Hi Geir,

Thanks for sharing your configuration. You said earlier in this thread that SimpleRetryConnectionStrategy is working fine for you with mule 2.0.2.
I also tried your configuration with Mule 2.02 & Activemq5.0. i am still facing the same problem with SimpleRetryConnectionStrategy. i have an inbound endpoint that subscribe to a topic. I shutdown my broker & when i bring the broker back online the endpoint is not able to receive anymore messages.
I am getting following error. Do you have any idea why i am getting this error? It would be great if you share your complete config file along with namespaces.

Thanks & regards,
JackyMule

Hi Geir,

Can you share your config file & SimpleRetryConnectionStrategy?
I want to have a look to it.

I am running on Mule 2.0.2

How do I prevent my Mule instance from shutting down when the ActiveMQ server is shut down.

I have implemented a SimpleRetryConnectionStrategy which works Ok, if I try to launch the Mule with no running ActiveMQ, and it gets it connection when when I the ActiveMQ has started up.
