camel wmq transactions - ack mode as TRANSACTED

Hi Team,

Please find the below scenarios or camel route

from("wmq:queue:eventQueue + "?useMessageIDAsCorrelationID=true")
.transacted()
.bean(orchestrator, "processMessage(${body}, ${headers})");

and for transaction i am maintaining JmsTransactionManager. please find the
same. actually i have gone through Chapter 9 in the Camel in Action book.
based on that I configured txn.

<bean id="wmq" class="org.apache.camel.component.jms.JmsComponent">
<property name="transacted" value="true" />
<property name="transactionManager" ref="txManager" />
</bean>
<bean id="txManager"
class="org.springframework.jms.connection.JmsTransactionManager">
<property name="connectionFactory" ref="wmqConnectionFactory" />
</bean>

Now in Chapter 9 in the Camel in Action book, author mentioned about
ACTIVEMQ.DLQ, but what will happen in case of Websphere MQ.
My requirement is if at all processMessage(${body}, ${headers}) fails to
process and throws exception , camel should not acknowledge and message
should be there as it is inside WMQ.

Could you please help me for the same.

Thanks
Satyajit
