Question

您好我正在尝试一起使用以下技术：

MyFaces 2.1.12
jstl 1.2
Apache 7

但是在尝试运行我的应用程序时，我得到以下异常：

java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester
    at org.apache.myfaces.config.impl.digester.DigesterFacesConfigUnmarshallerImpl.<init>(DigesterFacesConfigUnmarshallerImpl.java:42)

Caused by: java.lang.ClassNotFoundException: org.apache.commons.digester.Digester

这非常令人不安，因为我在项目中链接了commons-digester3-3.2.jar，将它放在“Web-INF”下的lib目录中并将其添加到java构建路径中......出了什么问题？

谢谢，

使用commons-digester 1.8版。 commons-digester3已经有很多变化。

java.lang.NoClassDefFoundError：org / apache / commons / digester / Digester Apache 7
