Properties configuration = new Properties();
          configuration.setProperty(ProcessService.DIRECTORY_ID, "default");
          configuration
                    .setProperty(ProcessService.PROJECT_PATH,
                              "C:\\Documents and Settings\\mm0c14214\\OracleBPMWorkspace\\GAT_PROCESS");
          try {
               ProcessService processService = ProcessService
                         .create(configuration);
               ProcessServiceSession session = processService.createSession(
                         crmForm.getUserId(), crmForm.getUserId(), "localhost");
               Arguments a = Arguments.create();
               a.putArgument("contactIdArg", crmForm.getContctId());
               a.putArgument("jobIdArg", crmForm.getJobid());
               a.putArgument("organizationIdArg", crmForm.getOrganizationId());
               a.putArgument("requestTypeArg", crmForm.getRequestType());
               InstanceInfo processinstance = session.processCreateInstance(
                         "/GATSERVICE", "BeginIn", a);
               processinstance = session.activityExecute(processinstance
                         .getActivityId(), processinstance.getId(), a);
               DynamicObject dynamicObject = session
                         .instanceGetData(processinstance);
               ArrayList productIdList = (ArrayList) dynamicObject
                         .asDynamicObject().getField("pIDList").asList();
               ArrayList productNameList = (ArrayList) dynamicObject
                         .asDynamicObject().getField("nameList").asList();
               HashMap map = new HashMap();
               for (int i = 0; i < productIdList.size(); i++) {
                    map.put(productIdList.get(i), productNameList.get(i));
               HttpSession httpSession = request.getSession();
               httpSession.setAttribute("list", map);
               httpSession.setAttribute("processinstance", processinstance.getId());
               httpSession.setAttribute("session", session);
               session.close();
               processService.close();
          } catch (Exception e) {
               e.printStackTrace();
