Interface FormController

All Superinterfaces:

Controller

All Known Implementing Classes:

AbstractUserProfileController

public interface FormController

extends Controller

FormController implementations provide the core business logic for the Struts forms. By delegating the work to controllers we reduce the complexity of the forms themselves and allow the busines-object to form population logic to be captured in one spot.

FormController s 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;
                                        action-controller=com.myapp.controller.SiteCopyController;
                                        summary-controller=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.
