Here is what I do: Map<String, Object> result = new HashMap<String, Object>(); result.put("Result", action); taskService.completeWithResults(taskId, userId, result); and I have the following error: java.lang.NoSuchFieldError: classLoader     at org.jbpm.task.utils.ContentMarshallerHelper.unmarshall(ContentMarshallerHelper.java:107)     at org.jbpm.process.workitem.wsht.GenericHTWorkItemHandler$TaskCompletedHandler.handleCompletedTask(GenericHTWorkItemHandler.java:260)     at org.jbpm.process.workitem.wsht.GenericHTWorkItemHandler$TaskCompletedHandler.execute(GenericHTWorkItemHandler.java:234)     at org.jbpm.task.service.local.LocalTaskService$SimpleEventTransport.trigger(LocalTaskService.java:329)     at org.jbpm.task.event.MessagingTaskEventListener.triggerPayload(MessagingTaskEventListener.java:76)     at org.jbpm.task.event.MessagingTaskEventListener.handleEvent(MessagingTaskEventListener.java:92)     at org.jbpm.task.event.MessagingTaskEventListener.taskCompleted(MessagingTaskEventListener.java:109)     at org.jbpm.task.event.TaskEventSupport.fireTaskCompleted(TaskEventSupport.java:49)     at org.jbpm.task.service.TaskServiceSession.postTaskCompleteOperation(TaskServiceSession.java:569)     at org.jbpm.task.service.TaskServiceSession.taskOperation(TaskServiceSession.java:495)     at org.jbpm.task.service.local.LocalTaskService.complete(LocalTaskService.java:83)     at org.jbpm.task.service.local.LocalTaskService.completeWithResults(LocalTaskService.java:91) So, I search in the code, and I find : MarshallerReaderContext context = null; context.classLoader = ContentMarshallerHelper.class.getClassLoader(); BUT... (something I can't explain), MarshallerReaderContext has no classLoader. This throws the error above. Someone knows? Any help would be apreciated. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/802416#802416] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
