   Lines 19, 20, 23, 24, and 27: These lines define the result type as Tiles and the

tile name, such as home and login, which is defined in tiles.xml. Depending

on the result string returned by the action, in other words, success or error, the

corresponding JSP file defined in tiles.xml is mapped with the definition name

in tiles.xml to the tile name in struts.xml.

Listing 4-35 illustrates the tiles.xml file.
