我在 jBPM 6.2.0 中运行 Deadline 任务时关闭了 EntityManager

这是日志跟踪。我在我的代码中没有看到我关闭实体管理工厂的任何地方。

没有问题我得到了这个问题的答案。我们没有初始化持久性 xml。以下语句的顺序很重要，我们在那里搞砸了。

<persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/jbpmDS</jta-data-source>
