Jakarta ee 在多场战争中将EJB部署到同一个应用服务器（Glassfish）

我们有一个jar文件，其中包含JPA实体bean和一个无状态会话bean，其中注入了EntityManager作为服务bean。服务bean具有以下注释：

@Stateless
@LocalBean
@EJB(name = "java:global/DataService", beanName = "DataService", beanInterface = DataService.class)

因为Glassfish可移植上下文名称包含war文件名（及其版本号），所以我们使用@EJB注释来定义一个与war文件名无关的名称

这个jar是一个依赖项/包含在两个单独的war文件中。war文件部署在同一台Glassfish（3.1.2.2）服务器中。我们在日志中发现了绑定问题，并认为问题在于类加载器。我曾多次尝试寻找如何将EJB部署到同一个应用服务器上，但都没有找到任何方法

有人能提供搜索词或给我指一个资源来解释EJB类加载，这可能有助于解决上述问题吗

根据要求，这里有一个示例异常，其中JPA jar文件包含在名为DataModelTest的测试war/应用程序中：

这难道不需要你把两场战争重新打包成一只耳朵吗，对于包含EJB的jar的单个副本？

请将异常stacktrace添加到问题中。您是否真的有此异常导致的任何问题，或者这是否只是在重新部署/取消部署时出现在日志文件中？我们在过去几天中尝试了许多方法，但没有看到绑定问题（不确定发生了什么变化）。我们在重新加载/重新部署应用程序时发现了问题，我为此创建了问题xxx。
