struts-blank能正常运行了，为什么struts-examples不能运行！！！！！！！

[cxy550]

我的jdk是1.4.1，tomcat是5.0.28，struts是1.2.1，安装完了后，ie中敲入"http://127.0.0.1:8080/struts-blank/"后显示出
Welcome!
To get started on your own application, copy the struts-blank.war to a new WAR file using the name for your application. Place it in your container's "webapp" folder (or equivalent), and let your container auto-deploy the application. Edit the skeleton configuration files as needed, restart your container, and you are on your way! (You can find the application.properties file with this message in the /WEB-INF/src/java/resources folder.)
应该表示我的blank没有问题了吧。
但"http://127.0.0.1:8080/struts-examples/"后却报错，这个目录不存在。我的目录肯定没有出错。
当我查看启动log文件的，发现出现了这么个错。

请问如何处理这个问题，我要运行struts，还有什么需要配置吗？目前我什么都没有配置。

我上那找了，没有找到类似的问题，能帮我解释一下吗？我现在把struts换成了1.2.5后不报错了，但出现了servlet的错，我没有修正任何的配置。
