MQTT topic subscription

I am using MQTT and activemq in which whenever message published on MQTT topic it will transfer to Activemq queue, below is my code.

<destinationInterceptors>
<virtualDestinationInterceptor>
    <virtualDestinations>
        <compositeTopic name="LOCAL.FOO.*">
            <forwardTo>
                <queue physicalName="LOCAL.FOO" />                      
            </forwardTo>
        </compositeTopic>
    </virtualDestinations>
</virtualDestinationInterceptor>

at the same time another application subscribing same MQTT Topic but that application doesn't get any message from topic but queue can get a message. So after activemq subscription no one can subscribe the same topic? If this is the case then what would be solution.

I dont have any idea about QoS level and retain falg.

You need to specify that this topic may also be used for subscriptions. There is a forwardOnly attribute that is true by default.

<compositeTopic name="LOCAL.FOO.*" forwardOnly="false">
    <forwardTo>
         <queue physicalName="LOCAL.FOO" />                      
    </forwardTo>
</compositeTopic>
