Thanks for the quickstart pointer! Very helpful. I have been using
different versions, ServiceMix 4.2 and 4.3, and Fuse ESB, so much that
it seems I'm starting to lose track myself....the ClassCastException
is from ServiceMix 4.2.
I will try to follow the quickstart on SM 4.3 and get back to the
issue after it. I guess I still need to introduce active mq bean and
broker:
<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent"
depends-on="my-broker">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
<broker:broker id="my-broker" useJmx="false" persistent="false"
brokerName="localhost">
<broker:transportConnectors>
<broker:transportConnector uri="tcp://localhost:61616"/>
</broker:transportConnectors>
</broker:broker>
? Those are not included the quickstart blueprint xml file (probably
since it is assumed they are configured somewhere else?).
