我正在将应用程序从Websphere 8.5.5.x环境迁移到自由20.0.0.3。除了JSF部分，我大部分都可以使用。初始化有问题，我无法弄清楚它是什么，也无法调试。由于该库是由自由提供的，所以我不能只放置断点来进行调试。
我可以提供以下比较

第一件事很奇怪，他在自由设置中做了两次，第二件事是ServletContext为'null'。
也许我缺少web.xml中的设置，或者faces-config.xml是错误的。我不确定，Websphere可能比自由要宽一些，并为我解决了一些问题。
有人在加载我的面孔方面有任何经验吗？

此ServletContext 'null' initialized消息是由较旧的MyFaces错误引起的：MYFACES-3356。不幸的是，Liberty jsf-2.0实现似乎没有解决此问题-与IBM一起打开支持记录很值得。
作为一种解决方法，如果它对您的应用程序可行，则可以通过<applicationManager autoExpand="true"/>在server.xml中启用应用程序扩展>
