I am facing issue while publishing messages to the IBM Websphere MQ Queue via PublishJMS processor.
Configuration of PublishJMS processor & JMS Controller Service,
It looks like you are hitting a known defect: APAR IT02814 (JMSCC0051: THE PROPERTY 'JMS_IBM_REPORT_PASS_CORREL_ID' SHOULD SET USING TYPE 'JAVA.LANG.INTEGER', NOT 'JAVA.LANG.STRING'.)
It states that pre-v7.0 IBM MQ Classes for JMS allowed passing a non-INT, v7.0 and higher are more strict. IBM has added a fix to v7.5.0.5 and to v8.0.0.2 to allow this to continue to work, the APAR also has suggestions on how to change the application to work without the fix.
