用.do调用action，出现问题，求前辈指教
<action-mappings><action path="/login"
scope="request"
type="com.yourcompany.struts.Action.loginAction"
parameter="login">
<forward name="success" path="/login2.do"></forward>
</action>
<action path="/login2"
scope="request"
type="com.yourcompany.struts.Action.login2Action"
parameter="login2">
<forward name="success" path="/MyJsp2.jsp"></forward>
</action>
</action-mappings>
这个是我xml里配置的 我点击MyJsp.jsp页面按钮，应该跳到login2啊 ，但是我这个报错了。
小弟是刚学不久，请前辈赐教啊~
/* 下面是myeclipse报错信息 */
严重: No action instance for path /login2 could be created

类型转换错误。。看看你的login2是个action吗。。 --------------------编程问答--------------------
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> --------------------编程问答--------------------
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？ --------------------编程问答--------------------
额。。Action是MappingDispatchAction的父类吧。。区别自己搜搜。。你怎么还在学struts1.. --------------------编程问答-------------------- 不同的类型 。 --------------------编程问答-------------------- 觉得 struts2 现在比struts1 用的多 ， 类型错误
补充：Java , Java EE
