JMS/MQRFH2 Message Properties in “other” Folder
On StackOverflow, someone asked about having an “other” folder (not “usr”) with an MQRFH2 (aka JMS) message. That day, I played around with a MQ/Java program that created various folders in an MQRFH2 message. i.e. When I ran a MQ/JMS program to retrieve the messages, the MQ/JMS programs simply ignore all folders outside of ‘mcd’, […]
