Answer 1

java.lang.ClassCastException: com.yourcompany.struts.Action.login2Action cannot be cast to org.apache.struts.action.Action
类型转换错误。。看看你的login2是个action吗。。

Answer 2

是呀   我在下面的action里创建了呀  <action path="/login2" 
    scope="request" 
    type="com.yourcompany.struts.Action.login2Action" 
    parameter="login2"> 
    <forward name="success" path="/MyJsp2.jsp"></forward>
    </action>

Answer 3

我知道了   我action的那个文件没有继承action    麻烦问一下  是不是继承Action就可以了？MappingDispatchAction跟继承Action有什么不同呀？

额。。Action是MappingDispatchAction的父类吧。。区别自己搜搜。。你怎么还在学struts1..

Answer 5

觉得 struts2  现在比struts1 用的多    ，  类型错误
