使用struts2框架产生的问题:
index.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8"%><jsp:forward page="/login/login.jsp"></jsp:forward>
login.jsp:
<%@ page language="java" pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %>
<script type="text/javascript">
function ini(){
document.form1.loginName.focus();
}
</script>

这里所填写的form表单 namespace="/login"action=" LoginAction_home.do",会造成的问题是：
There is no Action mapped for namespace [/] and action name [LoginAction_home] associated with context path [/itcast1109_project].
原因是因为".do"，
解决办法：方法一：把".do"去掉。
方法二：把namespace去掉，action改为"/login/LoginAction_home.do"
