    <result name="menuHome">/WEB-INF/page/menu/home.jsp</result>

Answer 2

If there is method="{number}", corresponding， the action config should have * in its name,

Example:

<action name="user_*" class="UserAction" method="{1}">

and in its corresponding jsp if has a form :

In that way, structs will let the user_userLogin action according to the user_*’s format analysis, and take out the * according the number 1, 2, 3 …, 1 means the first *.

If the action config like this:

<action name="user_*_*" class="com.xyz.{1}Action" method="{2}">

and the jsp form is like this:

<form action="user_Login_userLogin" method="post">

Its action will become like this:

class="com.xyz.Login" method="{userLogin}"
