javax.el.PropertyNotFoundException：目标不可达，标识符 bean 解析为 null

Question

当我尝试通过 Eclipse 部署我的应用程序时收到此错误消息，因为我通过 weblogic 控制台进行构建和安装包我的应用程序工作正常，但每次我从 Eclipse 部署我的应用程序时我的服务器正常但是当我尝试访问任何页面时都会收到此消息，如果有人可以帮助我，我将非常感激。下面是我的服务器日志。

我正在使用 weblogic 12 C bean 管理的 CDI。

我在 WL 12.1.3 中遇到了同样的问题：尝试通过 eclipse 将其部署为展开的存档（标准是虚拟应用程序）。

右键单击服务器 -> 属性 -> 展开主题 WebLogic -> 发布 -> 单击“发布为展开的存档”并应用更改
