Listing 4-19 illustrates the form that allows the user to enter a name and submit it.
Listing 4-19. index.jsp

4.<form action="hello">
5.<label for="name">Enter your name</label><br /><input type="text"
6.name="name" /><input type="submit" value="Submit" />
7.</form>
8.</body>
9.</html>
Line 4
: When the user submits the form, the action name
hello
is sent to the
container.
You need a mapping to map the URL to the
HelloWorldAction
controller. The mapping tells the
Struts 2 framework which class will respond to the user's action, which method of that class will be
executed, and which view will be rendered as the response. Listing 4-20 illustrates this mapping file.
