| <P> |
| An <strong>Action</strong> is an adapter between the contents of an incoming |
| HTTP request and the corresponding business logic that should be executed to |
| process this request. The controller (ActionServlet) will select an |
| appropriate Action for each request, create an instance (if necessary), |
| and call the <code>perform</code> method.</p> |
| |
| <p>Actions must be programmed in a thread-safe manner, because the |
| controller will share the same instance for multiple simultaneous |
| requests. This means you should design with the following items in mind: |
| </p> |
| <ul> |
| <li>Instance and static variables MUST NOT be used to store information |
| related to the state of a particular request. They MAY be used to |
| share global resources across requests for the same action.</li> |
| <li>Access to other resources (JavaBeans, session variables, etc.) MUST |
| be synchronized if those resources require protection. (Generally, |
| however, resource classes should be designed to provide their own |
| protection where necessary.</li> |
| </ul> |
| |
| <p>When an <code>Action</code> instance is first created, the controller |
| servlet will call <code>setServlet()</code> with a non-null argument to |
| identify the controller servlet instance to which this Action is attached. |
| When the controller servlet is to be shut down (or restarted), the |
| <code>setServlet()</code> method will be called with a <code>null</code> |
| argument, which can be used to clean up any allocated resources in use |
| by this Action.</p> |
