我做了很多＆＃39;在过去48小时内谷歌搜索这个，我仍然空白，所以我希望这里的问题可能会有所帮助。
我正在开发一个switchyard服务（实际上我将开发一整套它们，因此这种方法）我希望将基于JPA的dao代码和实体放在一个单独的jar中，以及作为其他DTO /接口的另一个jar。
这两个其他jar包含CDI bean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罐装入EE模块，因为这似乎是一个明智的事情，这给我带来了CDI注入的问题，因为我的开关站应用程序看不到豆子，但我意识到只是module.xml没有配置适当的依赖关系以允许焊接加载CDI bean。
之后，我无法将持久性单元加载到DAO中。无论我在模块中还是在switchyard app中都有persistence.xml，实体管理器都会保持null。 （我在module.xml中确实有javax.persistence）
有些人阅读模块让我相信JPA不会对这种方法有所帮助（如果有人能指出我如何使其工作，那将回答这个问题！）
所以我切换到试图将我的switchyard服务罐与其他两个罐子捆绑在EAR中。
我的耳朵结构是：
+-
sw-service.jar
dao.jar
dto.jar
+-META-INF
application.xml
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>
当我尝试部署时，我收到以下错误：

任何人都可以让我知道如何让切换器服务和JBoss模块之间的持久性单元，或者我在EAR文件中遗漏的内容，因为我完全不知道这个一个？
