In struts-config.xml
<controller processorClass="blah.blah.MyRequestProcessor"/>
My authentication filter used an atribute "authenticationRequired" in the
action mapping (note that this is not an elegant solution because it doesn't
follows the DTD specification)
<action-mappings
type="es.udc.is203.j2ee.eshop.http.controller.frontcontroller.EShopActionMap
ping">
<action path="/user/UpdateUserProfileDetails"
type="es.udc.is203.j2ee.eshop.http.controller.actions.user.UpdateUserProfile
DetailsAction"
name="userProfileForm"
scope="request"
input="/user/EditUserProfile.do"
validate="true"
authenticationRequired="true"/>
/**
* A filter to check if the action to be executed requires that the user had
* been authenticated. If the user has not been authenticated and the action
* requires it, <code>doProcess</code> returns the
<code>ActionForward</code>
* returned by <code>mapping.findForward("AuthenticationPage")</code>.
* <br>
* The uri of the action to be executed is stored in the request as
* <code>uri</code> and the parameters as <code>parameters</code> so them
can
* be retrieved later to continue the operation.
