No, source MQ queue and error MQ queue are different.
First I tried with single JMS "wmq" only. It didn't work so I thought of
creating two - one for regular consumer and another for error queue. However,
that didn't work either.
Unfortunately due to restriction put here, I cannot send whole XML.
Snippet of my context is -
1) Using onException -
<camel:camelContext id="mainroute"
xmlns="http://camel.apache.org/schema/spring"; trace="true">
<onException useOriginalMessage="true">
<exception>java.sql.SQLException</exception>
<redeliveryPolicy logRetryAttempted="true"
logRetryStackTrace="true" maximumRedeliveries="3"
retryAttemptedLogLevel="DEBUG"
retriesExhaustedLogLevel="ERROR" />
<handled>
<constant>true</constant>
</handled>
<bean ref="exceptionHandler"
method="exceptionPrint" />
<to uri="wmq:${error.queue}" />
</onException>
<route id="main-router">
<from uri="wmq:${source.queue}" />
<camel:bean ref="xmlToBeanProcessor" />
<recipientList>
<header>recipients</header>
</recipientList>
</route>
<route id="listHierarchy ">
<from uri="direct: listHierarchy " />
<camel:bean ref="ListHierarchyProcessor"
method="processSequence" />
</route>
</camel:camelContext>
<!-- JMS Setup -->
<bean id="wmq" class="org.apache.camel.component.jms.JmsComponent">
<property name="configuration">
<bean
class="org.apache.camel.component.jms.JmsConfiguration">
<property
name="connectionFactory" ref="connectionFactory" />
<property
name="concurrentConsumers" value="5" />
</bean>
</property>
</bean>
<bean id="connectionFactory" class="MQConnectionFactory">
<property name="queueManagerName"
value="${mq.queue.manager}" />
<property name="throwOnInvalidMessageProperty"
value="false" />
</bean>
2) Using dead letter queue
<camel:camelContext id="mainroute"
xmlns="http://camel.apache.org/schema/spring"; trace="true">
<route id="main-router"
errorHandlerRef="myDeadLetterErrorHandler">
<from uri="wmq:${source.queue}" />
<camel:bean ref="xmlToBeanProcessor" />
<recipientList>
<header>recipients</header>
</recipientList>
</route>
<route id="listHierarchy ">
<from uri="direct: listHierarchy " />
<camel:bean ref="ListHierarchyProcessor"
method="processSequence" />
</route>
</camel:camelContext>
<bean id="myDeadLetterErrorHandler"
class="org.apache.camel.builder.DeadLetterChannelBuilder">
<property name="deadLetterUri"
value="wmq:${error.queue}" />
<property name="redeliveryPolicy"
ref="myRedeliveryPolicyConfig" />
</bean>
<bean id="myRedeliveryPolicyConfig"
class="org.apache.camel.processor.RedeliveryPolicy">
<property name="maximumRedeliveries" value="1" />
<property name="redeliveryDelay" value="1" />
<property name="logHandled" value="true" />
<property name="logExhausted" value="true" />
<property name="logContinued" value="true" />
<property name="logRetryAttempted" value="true" />
<property name="logRetryStackTrace" value="true" />
<property name="logStackTrace" value="true" />
</bean>
<bean id="errorHandler" class="com.proj.testtoremove.ErrorHandler" />
<!-- JMS Setup -->
<bean id="wmq" class="org.apache.camel.component.jms.JmsComponent">
<property name="configuration">
<bean
class="org.apache.camel.component.jms.JmsConfiguration">
<property
name="connectionFactory" ref="connectionFactory" />
<property
name="concurrentConsumers" value="5" />
</bean>
</property>
</bean>
<bean id="connectionFactory" class="MQConnectionFactory">
<property name="queueManagerName"
value="${mq.queue.manager}" />
<property name="throwOnInvalidMessageProperty"
value="false" />
</bean>

Subject: Re: Not writing to Error queue
You use the same WebShere MQ queue manager for receiving the messages and
writing the failed messages, correct?
Could you please share the entire Spring XML configuration (including the
JMS component configuration). I'm a bit confused because you use 'wmq' and
'wmqError' as schema name. Did you also configured two JMS components? If
yes, why? If no, it cannot work...
Best,
Christian
