“AsynchBeans 服务未初始化”尝试查找 WebSphere 7 WorkManager 时出错

Question

我尝试使用 CommonJ WorkManagerTaskExecutor 作为 Quartz SchedulerFactoryBean 的任务执行器，以避免 WebSphere 中的非托管线程（描述为 此处--向下滚动到“Quartz With CommonJ” 部分）。不幸的是，我似乎无法查找任何默认的 WebSphere WorkManager，也无法查找我创建的任何默认 WebSphere WorkManager。 CommonJ WorkManager 的 Spring bean：

<bean id="taskExecutor" class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
    <property name="workManagerName" value="wm/default" />
</bean>

我收到 ServiceNotInitializedException：AsynchBeans Service 未初始化 错误和堆栈跟踪：

Exception in thread "P=166330:O=0:CT" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scheduler' defined in class path resource [spring-quartz-config.xml]: Cannot resolve reference to bean 'taskExecutor' while setting bean property 'taskExecutor'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taskExecutor' defined in class path resource [spring-quartz-config.xml]: Invocation of init method failed; nested exception is com.ibm.websphere.naming.CannotInstantiateObjectException: Exception occurred while the JNDI NamingManager was processing a javax.naming.Reference object.

有什么想法可以解决此问题吗？谢谢！

WebSphere asynchbean 只能从应用程序服务器进程使用。从堆栈跟踪中，您尝试从您编写的 TestQuartz 主方法中使用它，并且 asynchbeans 抛出异常以表明它没有在该 JVM 中作为服务器初始化的一部分启动。
