Mule - Unable to find type org.apache.activemq

Question

I am using Mule Studio 3.4 and would like to experiment with Active Mq. I understood that ActiveMq is embedded in Mule, so it's not necessary to add jars on the classpath, by the way activeMq classes cannot be found on the classpath. Where am I wrong? Here you are my configuration (copied from http://www.mulesoft.org/mule-activemq-integration-examples):

                          persistentDelivery="true" />

</mule>

The errors are "Unable to find type org.apache.activemq.broker.region.policy.IndividualDeadLetterStrategy on build path of project..." and similar others. Thanks!

Mule does not bundle activemq jars, nor the ones for any JMS broker, therefor you will need either to add it manually to your project or to the ${studio.home}/plugins/org.mule.tooling.server.${mule.version}_${mule.version}.${time.stamp}/mule/user if you want the container to provide it.

Thank you for your help, I downloaded the file activemq-all-5.8.0.jar and put it in the location you suggested. It has all the classes needed. I restarted eclpise but I still get the same errors. – user1820620 Sep 09 '13 at 12:32
Where did you put the jar? Also are you using eclipse or studio? – genjosanzo Sep 09 '13 at 12:55
I am using the studio, if I remove the attribute "p:queuePrefix="DLQ." in the first bean, the error is not shown! Pehraps it's not related to jar loading itself – user1820620 Sep 09 '13 at 13:07

I don't know what happened, but re-pasting the property again solved the problem. Then I couldn't reproduce the error! Your answer could anyway bring me to the next troubleshooting step, thank you. – user1820620 Sep 09 '13 at 13:27
