我在查詢使用jBPM5提供的任務服務分配給用戶的任務。我得到了一個偶然性的例外。問題查詢分配給用戶jBPM5的任務
的方式，通過它我查詢任務有一個方法，會取得用戶ID作爲參數調用。我正在使用人工任務服務API，它在內部使用自己的機制來查詢分配給用戶的任務。
public List<TaskSummary> getTasksAssignedToUser(String userId) {
TaskService taskService = this.humanTaskServiceHandler.getTaskService();
List<TaskSummary> taskSummary = taskService.getTasksAssignedAsPotentialOwner(userId, WorkflowConstants.LANGUAGE);
LOGGER.debug("TaskSummary found: " + taskSummary.size());
return taskSummary;
}
有時這種方法導致運行時異常如下面提到

我找不出是什麼原因造成上述錯誤，我怎麼能解決這個問題？使用
版本 -
- Spring框架（彈簧核心&彈簧豆） - 3.0.6.RELEASE
- 平臺 - 紅帽Linux - 2.6.18-308.el5
- 組織。 jBPM的文物版本 - 5.5.0.Final
更新
這是我如何配置實體管理jBPM任務服務

我使用的是相同的數據源（oracleDataSource）爲我的休眠層之一，它在這裏做什麼區別嗎？

問候， Mayank
我已經實現了一個獨立的hibernate層，負責其他CRUD操作，它只是共享數據源對象。我已經更新了我的問題，敬請看看。 – Mayank 2014-09-11 16:53:40
照顧什麼是CRUD？ – salaboy 2014-09-12 19:12:16
CRUD我的意思是創建，讀取，更新和刪除包含其他表來運行應用程序的數據庫的操作。 – Mayank 2014-09-15 10:46:02
