Using WebSphere MQ functions from JMS applications

By default, JMS messages held on WebSphere MQ queues use an MQRFH2 header to hold some of the JMS message header information. Many legacy WebSphere MQ applications cannot process messages with these headers, and require their own characteristic headers, for example the MQCIH for CICS Bridge, or MQWIH for WebSphere MQ Workflow applications. The section "Mapping JMS to a native WebSphere MQ application" in the chapter "JMS Messages" of WebSphere MQ Using Java covers these special considerations.
