少导包了。

[a514718137]

不能加载struts2的配置文件.检查配置是否正确.

[山鹰]

五个jar包 是否都全了

[无聊找乐]

严重: Exception starting filter struts2
Unable to load configuration. - [unknown location]
------------------------------------------------------------
现在的小孩都看不懂英文的？

[毛豆先生Max]

少jar包了

[老9]

配置文件，配置有错误。

[zengjz88]

是否缺少commons-logging.jar 包？

[morrisonleisure]

commons-logging 和 commons-logging-api 两个jar包 是否一样的？

[ch_ace]

看着真的像是少了jar文件

[xianaofei]

看看web.xml是否有配置不对的地方
另外架包要导入完整

[jumpheightway]

包未导入完整
初始化struts-default文件的时候就出错了

[xdrs1314]

java.lang.ClassCastException: org.apache.xerces.parsers.XML11Configuration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration
jar文件问题.

[renyanqun2010]

你可以用MyEclipse导入正常的Struts2 JAR文件，不同的框架版本应用的JAR包会有所不同，在你的异常信息中出现了类转换异常，说明你导入的JAR包有问题。

[Scott11Zhan]

少包、

[Scott11Zhan]

[Luciferoffans]

Caused by: java.lang.ClassCastException: org.apache.xerces.parsers.XML11Configuration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration，又见xerces果断删除该jar；顺便确认commons-logging.jar是否已添加。

[原来]

configuration 这个路径你指错了吧

[t427795737]

要么jar包没加，要么web.xml配置的不对
