Listing 4-28 illustrates the usage of several Struts 2 tags. This is a login form that allows the user
to input a username and password. In line 10, the name of the action
login
is sent to the container
when the user submits the form. This action name is mapped to
LoginAction
via
struts.xml
,
as illustrated in Listing 4-29.
