再问问，这个struts的流程没找出。。。

[trycatch2004]

这是个网上的例子，本身程序应该对的，能跑起来的，但我找不出这流程。。。
struts-config.xml文件内容如下：
<?xml version="1.0" encoding="ISO-8859-1" ?>

IndexAction.jsp内容如下：
<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
<%@ taglib uri="/WEB-INF/fmt.tld" prefix="fmt" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>

<c:redirect url="/initial.action"/>
～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
我的问题是：当从首页（IndexAction.jsp）登陆后，按IndexAction.jsp的内容转到initial.action，
后程序找到struts-config的下面段：
<action path="/initial"
type="hero.struts.actions.InitialAction"
scope="request"
validate="false">
<forward name="initial" path="indexDef"/>
</action>
但接下去indexDef转哪里去的？indexDef代表indexDef.do还是indexDef.action？
struts-config.xml文件里也没有哪项action的path属性值是indexDef，怎么回事？
（也不会是indexDef.java文件吧？我在文件夹下找过没找着这个文件）
