Struts 1.3 DispatchAction

[Rex Norm]

Hi,

I inherited a struts 1.3.10 app., and I'm trying to streamline all the classes with DispatchAction.

The current app has a class structure that looks like this:
appplicationClassXYZ (there are a lot of these) --> rootAction --> Action

rootAction is where admin duties are handled (in the execute() method) -- logging, checking that user is logged in, other junk ( filters may be best for some of this). To put all of these classes into one class, I notice from the Struts docs that I need to extend DispatchAction, but I don't override the execute() method or even deal with it in the subclass. So, the question is how can I handle admin duties such that every time superclass is called, the admin stuff, logging, etc. is taken care of? That is, don't I need to extend the execute() method? or do I put the admin stuff in a separate method in rootAction and be sure to call it for every method when I extend the DispatchAction? Seems like I should be able to encapsulate this.

this should be simple, but I'm not getting it. Just not sure how exactly DispatchAction works.

Hi,

As you have a rootAction in your current application which is extending a Action class, now you are planning to use a dispatch action now you could write a one class say RootDispatchAction extends DispatchAction ,

public class RootDispatchAction extends DispatchAction {
 public ActionForward execute(ActionMapping mapping,
                                 ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response)
        throws Exception {
         // write the admin stuff, logging, etc. which is in rootAction

         return super.execute(mapping, form, request, response);

        }
}

Now you can extend each of your action class from application extends to RootDispatchAction.

do I put the admin stuff in a separate method in rootAction and be sure to call it for every method when I extend the DispatchAction?

but i dont think there no need all those stuff repeated for me alteast.,am not doing like that.
one time is bit enough.
