我很好地在Eclipse中使用了Tomcat。现在，我无法启动服务器。尝试启动时出现以下异常。
一切都很好。我不知道有什么改变，但是显然有些改变。

SEVERE: 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>

Caused by: java.lang.ClassNotFoundException: org.apache.commons.digester.Digester
这只是告诉您在运行时类路径中缺少提到的类。如软件包名称所示，它是http://commons.apache.org/digester上的Apache Commons Digester。如果下载JAR文件并将其放在webapp运行时类路径所覆盖的路径之一（例如
/WEB-INF/lib）中，则此问题应消失。
