In this chapter, we have put into practice the theory we learned in the previous chapter about handling exceptions. We have explored the various mechanisms available for handling exceptions, including boundary events and event sub-processes. We have also explored the propagation of faults between processes.
Additionally, we have used some of the techniques we learned in earlier chapters, such as defining advanced conversations and correlation in order to create our practical examples.
We implemented two common patterns:
The "cancel message" use case that lets us send a message to a running process instance to cancel it
The "query" use case that lets us retrieve the value of process data objects from a running process instance
You are now armed with the theory and practical knowledge that you need to design quality BPMN processes that are able to communicate with each other safely, handle exceptions, and deal with data in arrays. Thank you for spending your time to learn with us!
