BTW if you are using ActiveMQ I'd recommend using the ActiveMQ component...

as this is then configured to use pooling correctly.


  <bean id="jms" class="org.apache.activemq.camel.component.ActiveMQComponent">
    <property name="brokerURL" value="tcp://somehost:61616"/>

Yes, right now its mandatory, it makes the CamelContext object which
is injected into the ProducerTemplate etc.

I think its gonna stay template AFAIK

If its any help there's a little tutorial on using camel with web apps...
