9. BPM and SOA in Concert > Initiating BPM from JMS

Initiating BPM from JMS

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. In this section, you will explore how to initiate a BPM process through JMS queue. The SalesToContract process is a part of the supplier process. Supplier_ABCS will be created, which will produce the QuoteRequest message on a JMS queue. 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. You will create a JMS queue and a Supplier_ABCS BPEL service to produce QuoteRequest, and finally, you will modify your SalesToContract BPM process to subscribe to this queue.
