我在 ocj4 服务器中部署了一个 ear 应用程序。当我尝试访问应用程序时，发生异常：
500 Internal Server Error
Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details.
我打开 application.log ：

我尝试搜索包含 MDSBackingStore 但未找到的 JAR 文件。问题是：我怎样才能得到那个罐子？
谢谢。
