Need Help Understanding AsyncWIH Implementation
I'm striving to run a process defined in BPMN2. I'd like to execute each node of the process and if one fails, I'd like to be able to stop the process, fix the problem that caused the crash and resume the process at the failed node. I was advised to use the AsyncWIH for this. I have a Spring configuration, and I'm using Hibernate 4, Spring 3.6, and JBPM 6.1.0, but the executor is from JBPM 6.2.0.
Here's where I create the environment and session:
