Problem with JMS Component with PooledConnectionFactory

["m.s." <da...@arcor.de>]

Hi,

I am using Camel 2.0-M2 with the JMS Component and ActiveMQ. I had some
performance issues until I discovered the hint in the documentation and
switched to the PooledConnectionFactory. It is configured like this: 

  <bean id="jmsFactory"
class="org.apache.activemq.pool.PooledConnectionFactory"
destroy-method="stop">
    <property name="connectionFactory">
      <bean class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://localhost:61616"/>
      </bean>
    </property>
  </bean>

  <bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
      <property name="connectionFactory" ref="jmsFactory"/>
  </bean>

The performance is much better now, but I have another problem. When I test
my application, I have a single queue from witch messages are not consumed.
At some point, it has 2110 pending messages and the application stops until
I purge the pending messages with the Web console.

I think it might be an issue with connection pooling and prefetching as
described here:
http://activemq.apache.org/what-is-the-prefetch-limit-for.html

With my configuration, is the PooledConnectionFactory only used for
Producers or also for Consumers?

Any help or useful hints on how to change my configuration is much
appreciated!

M.S.

Thanks, your both right. With the AMQ component, the performance is even
slightly better than with the JMS component and the PooledConnectionFactory
and I don't have the other problems anymore. Should have tried it earlier...

Yeah try the AMQ component that is optimized for Camel + AMQ.

I've experienced the same thing. Sometimes (and this isn't predictable) JMS
production ceases entirely and messages just back up. This isn't related to
load either - this can happen with near-zero load as well.

Issue does not happen with the JMS template or Camel's vanilla ActiveMQ
Component.

There is also another issue, but I am not sure if it is really related to the
PooledConnectionFactory. But I think since I use the
PooledConnectionFactory, the undeployment of my web application takes much
longer and sometimes it hangs completly. Has anyone experienced something
similar?
