| <DT>public abstract class <B>DispatchAction</B><DT>extends <A HREF="../../../../org/apache/struts/action/Action.html">Action</A></DL> |
| |
| <P> |
| <p>An abstract <strong>Action</strong> that dispatches to a public |
| method that is named by the request parameter whose name is specified |
| by the <code>parameter</code> property of the corresponding |
| ActionMapping. This Action is useful for developers who prefer to |
| combine many similar actions into a single Action class, in order to |
| simplify their application design.</p> |
| |
| <p>To configure the use of this action in your |
| <code>struts-config.xml</code> file, create an entry like this:</p> |
| |
| <code> |
| <action path="/saveSubscription" |
| type="org.apache.struts.actions.DispatchAction" |
| name="subscriptionForm" |
| scope="request" |
| input="/subscription.jsp" |
| parameter="method"/> |
| </code> |
| |
| <p>which will use the value of the request parameter named "method" |
| to pick the appropriate "execute" method, which must have the same |
| signature (other than method name) of the standard Action.execute |
| method. For example, you might have the following three methods in the |
| same action:</p> |
| <ul> |
| <li>public ActionForward delete(ActionMapping mapping, ActionForm form, |
| HttpServletRequest request, HttpServletResponse response) |
| throws Exception</li> |
| <li>public ActionForward insert(ActionMapping mapping, ActionForm form, |
| HttpServletRequest request, HttpServletResponse response) |
| throws Exception</li> |
| <li>public ActionForward update(ActionMapping mapping, ActionForm form, |
| HttpServletRequest request, HttpServletResponse response) |
| throws Exception</li> |
| </ul> |
| <p>and call one of the methods with a URL like this:</p> |
| <code> |
| http://localhost:8080/myapp/saveSubscription.do?method=update |
| </code> |
| |
| <p><strong>NOTE</strong> - All of the other mapping characteristics of |
| this action must be shared by the various handlers. This places some |
| constraints over what types of handlers may reasonably be packaged into |
| the same <code>DispatchAction</code> subclass.</p> |
