Its the same thing. Following is my process def : <?xml version="1.0" encoding="UTF-8"?> <definitions id="Definition" targetNamespace="http://www.jboss.org/drools"; typeLanguage="http://www.java.com/javaTypes"; expressionLanguage="http://www.mvel.org/2.0";

TaskClient client = new TaskClient(new HornetQTaskClientConnector(name, new HornetQTaskClientHandler(SystemEventListenerFactory.getSystemEventListener()))); BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler(); ContentData contentData = null; client.connect(ipAddress, port); try { contentData = ContentMarshallerHelper.marshal(map, null); client.complete(taskId, userId, contentData, responseHandler); responseHandler.waitTillDone(5000); BpmAPI.completeWorkItem(taskId); } catch(Exception e) { BpmExceptionHandler.handleException(e); } finally { if(client != null) { client.disconnect(); } } } In the map above I put a variable for next task. Only difference in the code is that I complete the task and then I complete the work item.
