jbpm计时器任务调用时发生错误

Question

我的jBPM 6.3工作流程中有一个用户计时器任务。当发生计时器任务时，我收到以下错误：

  

错误2016-06-01 17:35:53
  org.hibernate.engine.jdbc.spi.SqlExceptionHelper：146 -
  获取JdbcConnectionHandle的错误
  一个JdbcPooledConnection的   来自datasource jdbc / PostgresDS
  在州可达到的   使用计数1包装JDBC LrcXAConnection
  on org.postgresql.jdbc4.Jdbc4Connection@4baf9c1
  在JDBC LrcConnectionHandle上   处于状态NO_TX的JDBC LrcXAResource

我的工作流程似乎是

我的persistence.xml是：

    <persistence-unit name="dms-jbpm" transaction-type="RESOURCE_LOCAL">

        <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.BitronixJtaPlatform" />
    </properties>
</persistence-unit>

我无法理解我做错了什么。

我可以看到，jBPM核心引擎使用JTA进行持久化，你应该在persistence.xml中使用它（而不是resource_local）。不确定这是否是唯一的问题......
