Class JPAProcessInstanceManager

java.lang.Object
  org.jbpm.persistence.processinstance.JPAProcessInstanceManager

All Implemented Interfaces:

ProcessInstanceManager

public class JPAProcessInstanceManager
extends Object
implements ProcessInstanceManager

This is an implementation of the ProcessInstanceManager that uses JPA.

What's important to remember here is that we have a jbpm-console which has 1 static (stateful) knowledge session which is used by multiple threads: each request sent to the jbpm-console is picked up in it's own thread.

This means that multiple threads can be using the same instance of this class.
