Initiating BPM from JMS

Up to now, for all the phases of the BPM development lifecycle, you have used Human Tasks to initiate the BPM SalesToContract process. However, in real-time scenarios, this is rare case. Initiation of the BPM process takes place through either exposing the BPM process as a web service, through BPM reading a JMS, or through BPM PAPI APIs. Other mechanisms may include processes instantiated with e-mails/file/batch (that is, from enterprise information systems) and scheduled mechanisms, such as using timers.

Your SalesToContract process will consume those messages by subscribing to the same JMS queue. This will eventually lead to initiation of the SalesToContract BPM process.
