You need to have at least the process instance id or the work item id to get your things done.

session.startProcess("processName"); ---- This will always starts a new process

You have to get hold of your process instance or you can directly complete the work item if you have the work item id.

StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, null,

getEnvironment());

WorkflowProcessInstance inst = (WorkflowProcessInstance)ksession.getProcessInstance(<<process instance id>>);

……..get hold of the work item and complete it

                  OR

If you have the work item id already you can do this directly

ksession.getWorkItemManager().completeWorkItem(<<workitemid>>, null);

Subject: [rules-users] How do I resume a paused process?

I have a process that pauses after a few nodes are executed because it

reaches a Human Task node. I retrieve the persisted session with the

following code:

JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, null,

getEnvironment());

Once I have this session object I'm not sure how to resume the paused

process? I want to signal the Human Task work item as complete and have

the process resume at that point. I've tried this code:

WorkItemManager wm = session.getWorkItemManager();

wm.registerWorkItemHandler("Approve", new WSHumanTaskHandler());

WorkflowProcessInstance pi = (WorkflowProcessInstance)

session.startProcess("processName");

Object[] nodes = pi.getNodeInstances().toArray();

WorkItem wi = ((HumanTaskNodeInstance) nodes[0]).getWorkItem();

wm.completeWorkItem(wi.getId(), null);

session.dispose();

The result of this is that the workflow restarts from the first node and

completes to the end. I expected that the workflow would start at the

persisted location. What am I missing here?
