无法在 GlassFish 中使用 Jersey 启用 REST（抛出与 JPA 相关的异常）
Unable to enable REST with Jersey in GlassFish (throw an exception relevant to JPA)
我不明白为什么我无法启动我的 REST 服务。该异常说明了一些关于 JPA 的信息，但没有提供太多关于导致它的原因的信息。
如果在地址栏中输入 url: localhost:8080/UsersControl/api/all，GlassFish returns 一个 404 错误。

¿我做错了什么？感谢您的帮助和时间。
我想这只是答案的一半，因为它没有解决异常问题，但显然 REST 应用程序仍在运行，并进行了以下修复。
From comment:
Not sure about the exception, put your path is wrong. You define /api/ as the root application path in the web.xml. Then you define /api again in the @Path for the UserService. So it should be /api/api. But you most likely want to change the @Path to /users and use /api/users
