The MapMessage Input Mode is only available in a Messaging Client tool (a provisioning action tool) when JMS is selected as the Transport type, and javax.jms.MapMessage is chosen as the Message-Type. The MapMessage Input Mode allows you to Add, Modify, and Remove MapMessages by clicking the appropriate buttons.
MapMessages can also be Diffed by right-clicking the Messaging Client node and selecting Create Regression Controls from the shortcut menu.
