Tile's context attributes, and inserts the corresponding definition. If the path doesn't

match a definition, the

TilesRequestProcessor

lets the base

RequestProcessor

handle

the request.

Using this approach you can elminate almost all direct references to JSPs in your

struts config.xml file. You will end up with many actions and definitions; for each

action, you eliminate one JSP file that you would have had to maintain. Instead of

n

JSP pages, you will have

n

 actions mappings in your struts config.xml file.

Local and global forwards can use this technique. The common convention is to

specify definition names using a dot ( . ) separator instead of a slash ( / ).

For more information, check out the JavaDocs for the

TilesRequestProcessor

. These

are included with Struts, or you can find this documentation at http://struts.apache.org/

14.4 Creating Tabbed Panes

Problem

You want your pages to display as tabbed folders.

Solution

Use the Tiles Tabbed Layout. Example 14 7 shows the JSP page (tabsLayout.jsp) that

lays out components in a tabbed fashion.

Example 14 7. Tiles tabbed layout

<%@ taglib uri="http://struts.apache.org/tags bean" prefix="bean" %>

<%@ taglib uri="http://struts.apache.org/tags logic" prefix="logic" %>

<%@ taglib uri="http://struts.apache.org/tags tiles" prefix="tiles" %>

<%  

  Tabs Layout .

  This layout allows to render several tiles in a tabs fashion.

  @param tabList A list of available tabs. We use MenuItem to carry data (name, body,

icon, ...)

  @param selectedIndex Index of default selected tab

  @param parameterName Name of parameter carrying selected info in http request.

  %>

<%  

Use tiles attributes, and declare them as page java variable.

These attribute must be passed to the tile.
