Hi,

I've read an ActiveMQ article describing why not to use traditional JMS durable subscriptions at http://activemq.apache.org/virtual-destinations.html. In place of durable subscribers it suggests to use Virtual Topics and a Virtual Consumer Queue. I'm testing this using Camel 1.5.4. and have implemented a route from a Virtual Topic to a Virtual Consumer as:

from("activemq:topic:VirtualTopic.topic").to("activemq:Consumer.example.VirtualTopic.topic");

With the following added to the activemq.xml configuration file:

<broker xmlns="http://activemq.apache.org/schema/core">

<destinationInterceptors>

<virtualDestinationInterceptor>

<virtualDestinations>

<virtualTopic name=">" prefix="VirtualTopicConsumers.*." >

</virtualDestinations>

</virtualDestinationInterceptor>

</destinationInterceptors>

So my question is does this virtual consumer provide durability? For this route definition, will the topic hold the subscription until the consumer is connected? In preliminary tests I cannot confirm this, on the ActiveMQ Administration console the above example does not show the consumer as a "durable subscriber", which is probablly correct?

Seeking anyone's advice or experience with this subject.

Thanks.

-Gary
