From docs:
pub.prt.jms:sendWmPRT. Sends a JMS message. This service encodes an IS Document into a JMSmessage and sends it to the specified destination using the specified options. The maindifference between this service and the pub.jms:send service in WmPublic is that thisservice allows the user to easily specify the type of the document, which is required bythe Process Engine to kick off a process instance, as well as make it convenient to formatthe JMS message appropriately for use with the Process Engine.
