Thanks Sebastian. Infos below:
process definition : (Same as examples/taskform)

I am trying to get all history information of an process instance using Servlet and JSP.
Codes below :
ProcessManager:
| public ProcessInstaticeActivityInfo getActivityCoordinatesInfo(String
processInstanceId) {
| ProcessDefinitionImpl processDefinition = (ProcessDefinitionImpl) this
| .getProcessDefinitionByProcessInstanceId(processInstanceId);
| String pdId = processDefinition.getId();
| List<ActivityInfo> activeCoordinates = new ArrayList<ActivityInfo>();
|
| List<ActivityInfo> coordinateList = new ArrayList<ActivityInfo>();
| {
| ActivityInfo activityInfo = new
ActivityInfo(processDefinition.getInitial().getCoordinates());
| coordinateList.add(activityInfo);
| List<HistoryActivityInstance> activities =
historyService.createHistoryActivityInstanceQuery()
| .executionId(processInstanceId).list();
| for (HistoryActivityInstance activity : activities) {
| String activityName = activity.getActivityName();
| activityInfo = new
ActivityInfo(repositoryService.getActivityCoordinates(pdId, activityName));
| activityInfo.setActivityInstance(activity);
| coordinateList.add(activityInfo);
| }
| }
|
| HistoryProcessInstance hpi =
getHistoryProcessInstancByProcessInstanceId(processInstanceId);
| String endActivityName = ((HistoryProcessInstanceImpl) hpi).getEndActivityName();
|
| if (endActivityName != null) {
| ActivityCoordinates coordinates =
repositoryService.getActivityCoordinates(pdId, endActivityName);
| activeCoordinates.add(new ActivityInfo(coordinates));
| } else {
| Set<String> activityNames =
executionService.findExecutionById(processInstanceId)
| .findActiveActivityNames();
| for (String activityName : activityNames) {
| ActivityCoordinates coordinates =
repositoryService.getActivityCoordinates(pdId, activityName);
| activeCoordinates.add(new ActivityInfo(coordinates));
| }
| }
| return new ProcessInstaticeActivityInfo(activeCoordinates, coordinateList);
| }
|
Servlet:
| public void execute(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException

| ProcessManager pm = new ProcessManager();

| request.getParameter("taskid");
| String piId = request.getParameter("pid");
| ProcessInstaticeActivityInfo processInstaticeActivityInfo =
pm.getActivityCoordinatesInfo(piId);
| request.setAttribute("activeActivityInfos",
processInstaticeActivityInfo.getActiveActivityInfos());
| request.setAttribute("processedActivityInfos",
processInstaticeActivityInfo.getProcessedActivityInfos());
| request.setAttribute("pm",pm);
| response.setContentType("text/html;charset=UTF-8");
| RequestDispatcher dispatcher =
request.getRequestDispatcher("st_view.jsp");
| dispatcher.forward(request, response);
| }
|
jsp:
| ProcessManager pm = (ProcessManager)request.getAttribute("pm");

|
position.append("height:").append(coordinates.getHeight()-10).append("px;");
|
position.append("width:").append(coordinates.getWidth()-10).append("px;");
| StringBuffer text = new StringBuffer();
|
| if (activityInstance instanceof HistoryDecisionInstanceImpl) {
| text.append("<b>CompleteTime:</b>
").append(activityInstance.getEndTime());
| String transitionName = ((HistoryActivityInstanceImpl)
activityInstance).getTransitionName();
| if("completed".equals(transitionName)){
