我目前正在开发在jDeveloper 11g第1版，Oracle 11g数据库，独立的WebLogic服务器10.3中开发的企业应用程序。我们计划将整个应用程序迁移到12c。
迁移后，我们的应用程序可以在集成环境中的jDeveloper 12.2.1.3版本中顺利运行。但是，当我们尝试在独立的weblogic 12.2.1.3中部署应用程序（.ear文件）时，我们遇到了麻烦。
我们不得不将Oracle数据库从11gR1迁移到12c。解决了许多错误之后，我们已成功登录系统，并进入我们的Welcome.jsf页面。现在，当在动态选项卡中呈现视图对象时，我们面临一个错误。基本上，视图对象无法在动态UI外壳中呈现。
