Answer 1

提示是你缺少 struts2-core-2.1.8.jar
你去
www.apache.org
上去下载struts2的类库

然后，把你导入的工程中依赖的包都修改一下。

F:/ProgramFiles/apache-tomcat-6.0.36/webapps

我不确定这个目录是你的tomcat所在的目录，这个是不是你导入的项目中所使用的，
而不是你本地的目录？

Answer 2

MS Struts的 .jar 或者不兼容有冲突、或者还缺少别的

Answer 3

struts2的配置文件有错或者是包有冲突了

Answer 4

Caused by: Bean type class com.opensymphony.xwork2.ObjectFactory with the name xwork has already been loaded by bean

你这个不是jar包冲突么。

struts2-core-2.1.8%20.jar!

struts2-core-2.1.8.jar!

这个两个包冲突了吧，去掉一个

Answer 5

好像是你的struts2有问题，先检查你的配置文件在检查JAR包
