jbpm定时器任务调用时出错

Question

我的 jBPM 6.3 工作流中有一个用户计时器任务。当定时器任务发生时，我得到以下错误：

ERROR 2016-06-01 17:35:53
org.hibernate.engine.jdbc.spi.SqlExceptionHelper:146 -
error enlisting a JdbcConnectionHandle
of a JdbcPooledConnection
from datasource jdbc/PostgresDS
in state ACCESSIBLE
with usage count 1 wrapping a JDBC LrcXAConnection
on org.postgresql.jdbc4.Jdbc4Connection@4baf9c1
on a JDBC LrcConnectionHandle
on a JDBC LrcXAResource in state NO_TX

我的工作流程看起来像

我的 persistence.xml 是：

    <persistence-unit name="dms-jbpm" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>

    <mapping-file>META-INF/JBPMorm.xml</mapping-file>

        <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。

我能看到的一件事是，jBPM 核心引擎使用 JTA 进行持久化，您应该在 persistence.xml 中使用它（而不是 resource_local）。不确定这是否是唯一的问题...
