Description of problem: Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1.Create workitemhandler in JBDS as follows... public void executeWorkItem(WorkItem workItem, WorkItemManager manager) { // extract parameters String snd_message = (String) workItem.getParameter("SecondMessage"); System.out.println("Prabakar ::: " + snd_message); Map<String,Object> results = new HashMap<String,Object>(); results.put("Result", "Ak"); manager.completeWorkItem(workItem.getId(), results); } 2.Update your workitemdefinition information as follows... [ "name" : "SecondNotification", "parameters" : [ "SecondMessage" : new StringDataType(), ], "results" :[ "Result" : new StringDataType() ], [ "icon" : "com/icon/world.png", "displayName" : "Get" ] 3. Call the process in main method in JBDS public static final void main(String[] args) { try { KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.getKieClasspathContainer(); KieSession kSession = kContainer.newKieSession("ksession-process"); kSession.getWorkItemManager().registerWorkItemHandler("SecondNotification", new SecondWorkingHandler()); Map<String, Object> params = new HashMap<String, Object>(); params.put("MyResultParam", "Prabakar"); kSession.startProcess("com.sample.bpmn.hello", params); } catch (Throwable t) { t.printStackTrace(); } } Actual results: ...
