Reading and writing messages into MQ from WAS Liberty - ibm-mq

Question

We were trying to send MAP (java.util) using JMS template , but at the client side we are unable to read the message and during the server start up , spring boot #JMSListener complains with the following message , this works fine with WAS 7 but doesnt with WAS Liberty 8.5.5 , iam also including the code snippet and also the different message format's that we are receiving for the different versions of server . Did any thing changed in WAS Liberty ?

Answer 1

WebSphere MQ messages are being put by my application(JMS application) to a queue. These messages are to be picked up by a jms application. I have misunderstood targetClientId option available thinking that the targetClientId needed to be mentioned as "mq" if the messages where we write is an MQ but its not the case .We need to set targetClientId as MQ only if we the messages are processed by non-jms application. As i was setting the targetClientId as 'MQ' its stripping the RFH headers needed for the JMS application to process the message and parsing fails at the consuming application .
<jmsQueue id="MYAPP_QUEUE" jndiName="jms/test/testq">
<properties.wmqJms
baseQueueName="MYAPP.TEST.A"
persistence="PERS"
targetClient="MQ"/> -- removed this
</jmsQueue>
