	&lt;p&gt;What is your name?</p>&lt;/p&gt;

	</form>

</body>
</html>&gt;&lt;/p&gt;
	&lt;/form&gt;

&lt;/body&gt;
&lt;/html&gt;

Create the Action class

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

Hmmm, you did not enter a name. Please try again!

&lt;/body&gt;
&lt;/html&gt;

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.

     </action>&lt;/action&gt;

  </package>
</xwork>&lt;/package&gt;
&lt;/xwork&gt;

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

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!"
