The first snippet redirects to a Struts ActionForward named welcome.
This places controls within the Struts controller where it can be
managed from the struts-config.
In the global-forwards section, the ActionForward element for welcome
is mapped to the page /do/Menu. This application uses prefix mapping,
so any request for /do/* is sent to the Struts ActionServlet. The Struts
ActionSerlvet then looks for a matching ActionMapping.
The matching ActionMapping in this case is /Menu (the URI stripped of
the prefix or suffix registered to the Servlet). If you look again, I
think you will find this ActionMapping:
action path=/Menu name=menuForm
type=org.apache.struts.scaffold.ExistsAttributeAction
parameter=application;HOURS
forward name=success path=.article.Menu/
forward name=failure path=/do/MenuCreate/
/action
Here, if the attribute exists, the page will be rendered by the
.article.Menu Tile. Otherwise, control will go the /MenuCreate action
first.
The .article.Menu tile (in tiles-def.xml) assembles the page using these
instructions:
definition name=.article.Menu extends=.article.Base
put name=title value=article.Menu.title/
put name=content value=/article/content/menu.jsp/
put name=navbar value=/article/common/navbarMenu.jsp/
/definition
The menu.jsp is the main content page, but other pages are also used to
create the final response.

I am studying the code in Artimus_1_1 to make sure
that I understand how things actually work. I am lost
at the beginning of the application. Please kindly
help me. The index.jsp of the application contains
two lines:
code:
--
%@ taglib uri=/tags/struts-logic prefix=logic %
logic:redirect forward=welcome/
---
Does this redirect forward tells the browser to submit
a new request to the path with logical name welcome?
I then searched the config.xml file,
code:
---
global-forwards
!-- default forwards --
forward
name=baseStyle
path=/article/assets/styles/base.css/
!-- MENU forwards --
forward
name=welcome
path=/do/Menu/
forward
name=cancel
path=/do/Menu
redirect=true/
forward
name=done
path=/do/Menu/
...
/global-forwards
---
The path of the logical name welcome is do/Menu
(note it is upper case Menu). The other place that
do/Menu appears in the config.xml is:
action
path=/MenuCreate
name=menuForm
type=org.apache.struts.scaffold.ProcessAction
parameter=org.apache.artimus.article.MenuCreate
forward
name=success
path=/do/Menu/
forward
name=failure
path=.article.Menu/
/action
There is no Menu ActionServlet in the application.
There is a menu.jsp (note it is lower case menu) file
in the application. Does this application display
menu.jsp when it is first launched? Apparently, it
does. This menu.jsp is in the
artimus_1_1/WEB-INF/src/pages/article/content folder.
I am confused - does /do/Menu locate the menu.jsp
1. in the /src/pages/article/content folder?
2. regardless upper or lower cases?
