Java 与CDI的跨库依赖关系

在过去的48小时里，我已经在谷歌上搜索了很多，但我还是一无所获，所以我希望这里的一个问题可能会有所帮助

我正在开发一个开关站服务（实际上，我将开发一整套开关站服务，因此采用这种方法），我希望将基于JPA的dao代码和实体放在一个单独的jar中，以及另一个用于其他DTO/接口的jar中

这两个其他jar都包含CDIBeans和beans.xmls，DAO jar包含一个有效的persistence.xml，它连接到我的JBoss应用服务器中的JDNI数据源

我最初的想法是将两个JAR都作为EE模块加载，因为这似乎是一件明智的事情，这给了我CDI注入方面的问题，因为我的开关站应用程序看不到bean，但我意识到这只是module.xml没有配置适当的依赖项以允许weld加载CDI bean

然而，在那之后，我无法将持久性单元加载到DAO中。实体管理器一直显示为空，无论我在模块中还是在开关站应用程序中使用persistence.xml。（我在module.xml中有javax.persistence）

一些关于模块的阅读让我相信JPA在这种方法上是行不通的（如果有人能告诉我如何使它起作用，这将回答这个问题！）

所以我转而尝试将我的开关站服务罐和另外两个罐捆绑在一起

我的耳朵结构是：

+-
  sw-service.jar
  dao.jar
  dto.jar
  +-META-INF
    application.xml

而我的application.xml包含

<application>
    <module>
        <java>sw-service.jar</java>
    </module>
    <module>
        <ejb>dao.jar</ejb>
    </module>
    <module>
        <ejb>dto.jar</ejb>
    </module>
</application>

有人能告诉我如何让持久化单元在开关站服务和JBoss模块之间穿行吗，或者我的EAR文件缺少了什么，因为我对此完全不知所措
