| <p>An action responds to a request. Writing an action means subclassing one of the Action classes and then overriding the class's <code dir="ltr">execute</code> method. An ActionForward is returned by the <code dir="ltr">execute</code> method. |

| <p>Before you can use the New Struts Action wizard, you must have a Struts configuration file. To create a Struts configuration file quickly and efficiently, right-click the project node, choose <b>Properties</b> and use the Frameworks panel. Not only does this provide you with a Struts configuration file, but you also get the Struts libraries and supporting files.</p> |
| <p>Once you have a Struts configuration file, you open the New Struts Action wizard by right-clicking a web application, choosing <b>New</b> > <b>Other</b> and selecting Struts Action from the Struts category.</p> |
| <p>In the <b>Name and Location</b> page, you set the following properties:</p> |
