	&lt;/form&gt;

Create the Action class

The HTML form submits an attribute called "name", and the Action class provides a corresponding JavaBean property.

...

We can just add a new action mapping to the file we started in the Hello World lesson.

Try it!

If you are coding along, go ahead and try your form now. Open the input page (http://localhost/tutorial/helloName.html), and click the submit button to see what happens. Try it with and without entering a name.

Create the success and error pages

We can use the same error page, but we'll need a slightly different success page helloName2-success.jsp. The only difference is the <saf:property> tag.

Code Block

&lt;%@<%@ taglib uri=&quot;action2&quot;"action2" prefix=&quot;saf&quot; %&gt;
&lt;html&gt;
&lt;head&gt;
  &lt;title&gt;Success"saf" %>
<html>
<head>
  <title>Success Page - Without Using Getters and Setters&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
  &lt;p&gt;Setters</title>
</head>
<body>
  <p>
    Hello, &lt;saf<saf:property value=&quot;"parameters.yourName&quot;" /&gt;>!
  &lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;</p>
</body>
</html>

Try it!

Go ahead and try it now. Load helloName.html, enter "Bob" in the text field, and click the form submit button. You should see helloName2-success.jsp saying "Hello, Bob!"
