An abstract?Action?that dispatches to a public method that is named by the?parameter?attribute of the corresponding ActionMapping. This is useful for developers who prefer to combine many related actions into a single Action class.
To configure the use of this action in your?struts-config.xml?file, create an entry like this:
   <action path="/saveSubscription"           type="org.example.SubscriptionAction"           name="subscriptionForm"          scope="request"          input="/subscription.jsp"      parameter="method"/> 
where 'method' is the name of a method in your subclass of MappingDispatchAction that has the same signature (other than method name) of the standard Action.execute method. For example, you might combine the methods for managing a subscription into a single MappingDispatchAction class using the following methods:
