Hi again.
I recently encountered that the redeliveryPolicy still doesn't work as
expected. Basically it does the redelivery - but with default settings as it
seems.
Tried this configuration in activemq.xml with camel 1.4 snapshot:
<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring";>
<route errorHandlerRef="deadLetterErrorHandler">
<from uri="activemq:NEW" />
</route>
</camelContext>
<bean id="deadLetterErrorHandler"
class="org.apache.camel.builder.DeadLetterChannelBuilder">
<property name="redeliveryPolicy" ref="redeliveryPolicyConfig"/>
</bean>
<bean id="redeliveryPolicyConfig"
class="org.apache.camel.processor.RedeliveryPolicy">
<property name="maximumRedeliveries" value="3"/>
<property name="initialRedeliveryDelay" value="10000"/>
<property name="useExponentialBackOff" value="true"/>
<property name="backOffMultiplier" value="2" />
</bean>
Redelivery takes place in 30 seconds with a retry count of 5 instead of the
values configured. This might be because the errorHandlerRef on route isn't
evaluated at all. If I change this to foobar, it doesn't complain about it
on startup.
So what I'm doing wrong?
Regards,
Veit
