JBPM6: How to resume a process from the last successful node after a server failure?

I am trying to implement a strategy for switching to another resource while executing jbpm6 processes. My setup is this:

  • I am using jbpm6.2.0-Final (latest stable version) with support enabled.
  • I create an instance of org.kie.spring.factorybeans.RuntimeManagerFactoryBean with type SINGLETON to get KSession to start / stop processes and terminate / abort work items
  • all beans are connected to Spring 3.2
  • DB2 uses a database engine
  • I am using Tomcat 7.0.27

In a positive scenario, everything works as I expect. But I would like to know how to resume the process in case of server failure. To reproduce it, I started my process (described as a BPMN2 file), got to some middle step and killed the Tomcat process. After that, I see an incomplete process instance in the PROCESS_INSTANCE_INFO table and an incomplete work item in the WORK_ITEM_INFO table. There is also a session in the SESSION_INFO table.

My question is: could you show me an example of code that will take this remaining process and resume it starting from the last node (if possible).

Update I forgot to mention that I do not use the jbpm console, but I embed jbpm in my javaee application.

If you initialize your RuntimeManager when the application server starts, it should take care to restart and resume processes. You do not need to worry about restarting it again.
