Problem subscribing to a topic after machine wakes from sleeping

Hi there,

I have a broker on machine A that publishes a topic for machine B to
subscribe to. Machine A shuts down each night at 12am and powers up at 5am.
Machine B sleeps at 12am and wakes up at 5am (as distinct from powering
down/up; just in case this is relevant).

What I'm finding is that when machine B sleeps/wakes it does not appear to
be connected to the topic any longer. I have verified this by observing that
there is no ActiveMQ.Advisory.Consumer.Topic.&lt;topicname&gt; after about
12am (my Hyperic monitoring tool confirms this). In addition when I look at
the AMQ console on machine A after 5am, there is no connection for machine B
(where there was one the night before).

If I restart my subscriber application on machine B then all is again well.

I'm using AMQ v.5.3.1. In addition here is my Spring configuration for
subscribing for the topic:


  &lt;bean id="activeMQConnectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory"&gt;
    &lt;property name="brokerURL"
      value="tcp://192.168.1.13:61616" /&gt;
  &lt;/bean&gt;
  &lt;bean id="jms-receiver"
class="org.apache.activemq.camel.component.ActiveMQComponent"&gt;
    &lt;property name="connectionFactory" ref="activeMQConnectionFactory"
/&gt;
  &lt;/bean&gt;


Any ideas on what I may be able to do to circumvent the issue I'm seeing?

Kind regards,
Christopher

Turns out that this is a Spring 2.5.6 issue and that one has to upgrade to
Spring 3 to resolve it. Please see the discussion on the Camel forum for
more information:
