In Listing 4-29, line 13 maps the LoginAction class of the login name to the URL, and line 14
renders home.jsp when the String success is returned by the LoginAction class. If the LoginAction
class returns the String error , then login.jsp is rendered again with the error message.
Listing 4-30 illustrates LoginAction .
