extends Controller

ActionController implementations provide the core business logic for the Struts actions.

By delegating the work to controllers we reduce the complexity of the actions themselves and allow the business logic to be captured in one spot. Controllers are dynamically loaded by the actions and so updating business logic can be a simple matter of adding a new jar with the right controllers, and updating the struts-config.xml file. Eg:

         <action
                path="/admin/handleeditsitecopy"
                type="org.davesag.generica.servlet.action.HandleUpdateAction"
                parameter="pipe=editsitecopy;
                                        form-controller=com.myapp.controller.SiteCopyController;
                                        saver=com.myapp.controller.SiteCopyController;
                                        summariser=com.myapp.controller.SiteCopyController"
                name="sitecopy"
                scope="request"
                validate="true"
                input="/admin/editsitecopy.do">
                <forward name="success" path="thanks.editsitecopy.page"/>
        </action>
 

Note in the above example all three controllers are embodied in the same class.
