Re: IBM MQ and "replyTo" useage - not working

[Claus Ibsen <cl...@gmail.com>]

Hi

Do you have activemq-camel on the classpath, if so it has type
converters for String -> queue instance and hence creates an
ActiveMQQueue.

You likely need to create a IBM queue instance as a <bean> etc and
refer to that in the <setHeader>

Something on the line of

<bean id="myReplyQueue" class="com.ibm....MQQueue">
  <constructor ...>
</bean>


And then

<serHeader ...>
   <simple>${ref:myReplyQueue}</simple>
...
