我已将应用程序的运行时服务器环境从 Tomcat 7 更改为 Tomcat 8.5。它在我的 Eclipse IDE 开发环境中加载良好，但myfaces在生产环境中出现一些相关错误，即 Linux Slackware 14.2。
文件中的异常catalina.out：

文件中的异常localhost.log：
30-Jun-2020 02:13:07.103 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStop Exception sending context destroyed event to listener instance of class [org.apache.myfaces.webapp.StartupServletContextListener]
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

任何人都可以帮助弄清楚究竟是什么阻止了这个加载吗？我也可以发布其他配置文件。
非常感谢您的帮助！
