我正在尝试使用嵌入的OpenEJB作为环境与Arquillian进行集成测试，但是由于缺少persistence.xml，部署失败。
它正在多模块Maven项目的模块（“服务”）中运行。该模块作为EJB-Jar（“ services.jar”）部署在EAR（“ services-ear.ear”）中。同样在EAR中，我将项目的另一个模块（“数据”）的jar（“ data-1.0-SNAPSHOT.jar”）作为库包含在内。后一个模块将实体pojos和DAO保存为EJB。所有的DAO都有一个EntityManager，它引用在/data-1.0-SNAPSHOT.jar中的/META-INF/persistence.xml中声明的持久性单元。因此，EAR中的结构为：
ear
|- services.jar
|- /lib/data-1.0-SNAPSHOT.jar
|- ...
当我建立部署耳朵以验证这些组件确实在存档中时，该结构即被打印出来。 当我运行集成测试时，出现OpenEJB（“ 15：45：48.345 [LogStreamAsync.Thread] INFO OpenEJB.server-Ready！”），并且构建和部署了归档文件。 OpenEJB在“ data-1.0-SNAPSHOT.jar”中找到EJB，并开始部署它们。但是，它随后无法在同一jar中找到persistence.xml。我已经验证了persistence.xml在jar中。对于每个EJB，我得到的消息都是相同的：
