"Is it possible to get the StatefulKnowledgeSession/processInstance from solely its ID?" To view the discussion, visit: https://community.jboss.org/message/751749#751749 -------------------------------------------------------------- Hi, I have some questions on how to obtain the StatefulKnowledgeSession or processInstance that is running concurrently with another program. >From the documentation, it states that it's possible to make external calls >using * processInstance.signalEvent(type, eventData); * ksession.signalEvent(type, eventData); When I run my first .java file, I stored the current ksession.getId() and processInstanceId into a xml file and have a signal node at the converging gateway to wait for external signaling before continuing with the workflow. https://community.jboss.org/servlet/JiveServlet/showImage/2-751749-19140/externalSignaling.JPG https://community.jboss.org/servlet/JiveServlet/downloadImage/2-751749-19140/450-99/externalSignaling.JPG After that, I ran another bpmn workflow that reads the xml file for both the ksession ID and processInstance ID. However, I do not know how to use those 2 information to signal the signal node from the first bpmn workflow to continue with the workflow. (I was able to print out the String reperesentation of the 2 IDs but whenever I create a new ksession and do ksession.getWorkItemManager().registerWorkItemHandler("Signaling", new Signaling(ksession.getProcessInstance(Id))); I kept getting nullPointerException ) -Signaling is a service node that does either ProcessInstance.signalEvent("Signal", null); or session.signalEvent("Signal", null); (Tried both ways but didn't work) Any help is greatly appreciated. Thanks in advance!
