那的确就是包出了问题，检查与struts2相关的包
action有数据？但是页面的标签没有是吗，假如是的话，贴出页面的代码看看。
你把jsp 中的iterator标签的 id 去掉，改为
[code="java"]
/s:iterator [/code]
1，你是通过你的这个action来跳转到这个jsp的么？
2，可以贴出web.xml
你的list有get set方法吧。
你可以先在jsp页面上写 判断list是否有值
如果有值，你查下是否有的jar冲突
你不会没有xwork2.jar包吧。
jar包的作用不一样的，你写数据库成功与struts也没有关系。你还是看看jar包对不对吧
有没有多余的比如两个xwork
如果以上都没有错误，那就有可能是web。xml中配置问题了，你把web.xml改成
[code="java"]
struts2
org.apache.struts2.dispatcher.FilterDispatcher
struts2
/*
org.springframework.web.context.ContextLoaderListener
[/code]
javax.servlet.ServletException: java.lang.NoSuchMethodError: com.opensymphony.xwork2.util.ValueStack.findValue(Ljava/lang/String;Z)Ljava/lang/Object;
你的Action方法里面setlist（list）是什么意思
你已经把数据存到LIST集合了下面就不用写了 然后JSP页面就像你这样写
你的代码没有什么问题都是对的不知道你的包在网上搜索一下struts2的包吧
你如果实在解决不了就把你工程发给我 我帮你调式下
