我们使用Websphere 8 Application Server，我想在webapplication中使用服务器workmanager。我正在尝试获取对jca workmanager javax.resource.spi.work.Workmanager的引用，以便将其与Springs org.springframework.jca.work.WorkManagerTaskExecutor一起使用。
web.xml中的resource-ref如下所示：
<resource-ref>
<res-ref-name>workmanager/web</res-ref-name>
<res-type>javax.resource.spi.work.WorkManager</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
使用该配置，我得到以下异常：
Caused by: com.ibm.ws.asynchbeans.exception.AsynchBeanException: ASYN0064E: The value javax.resource.spi.work.WorkManager of the res-type resource reference element WorkManager is not right. Only the following values are allowed: com.ibm.websphere.asynchbeans.WorkManager, commonj.work.WorkManager.

它在这里说我的resource-ref必须是com.ibm.websphere.asynchbeans.WorkManager或commonj.work.WorkManager类型。它们都不是从JCA-Workmanager-Interface延伸出来的。
如果我将资源类型切换为commonj.work.WorkManager并在我的应用程序中使用弹簧org.springframework.scheduling.commonj.WorkManagerTaskExecutor，那么一切正常。
要让JCA Workmanager与Websphere一起工作，我是否需要在服务器端配置一些特殊的东西？我还没有在管理控制台中找到任何设置来切换实现。 Websphere 8支持Java EE 6，因此它应该能够处理JCA。
答案 0 :(得分：1)
为什么要使用特定于JCA的WorkManagerTaskExecutor而不是commonj？ JCA WorkManager仅供资源适配器使用，而不是由任意EE组件引用，而JCA特定的WorkManagerTaskExecutor的Spring documentation与之一致：
这主要用于JCA ResourceAdapter 实施
只需使用commonj WorkManager和相应的WorkManagerTaskExecutor。
