Hello,

We are trying to sending a message from a Java base application using JMS. There is a need to set a custom ID to the Message ID filed in MQMD while sending the message to the queue. Please note that we are connecting to a remote queue manager using Client Connection channel while dropping the message. We are seeing that whatever we try to set will get overwrtitten by a system value.

Can you please advise if there is a restriction on setting our own ID or are we doing something wrong here?

Thanks and Regards,
Viswas Gangarapu

Show us the code you are using to set the Message Id from a JMS application. I would advise against it. You should use the Correlation Id instead.

we had a few places where we needed to preserve the incomming MQ msg-id from a JMS message (since we had some applications that acted as a broker). And needed to set the same MQ msg-id on the outgoing JMS message. Maybe this snippet of camel/xml code can help you on your way
<simple>${properties:endpoint.jmscomponent.prefix} starts with 'wmq'</simple> <!-- default server configuration -->
<!-- JMSMessage is being geprefixd with "ID:", we need to strip this -->
<setBody>
<simple>${exchangeProperty.incomingJMSMessageID.substring(3)}</simple>
</setBody>

<bean beanType="com.ibm.msg.client.commonservices.Utils" method="hexToBytes"/>
<setHeader name="JMS_IBM_MQMD_MsgId">
<simple>${bodyAs(byte[])}</simple>
</setHeader>
