I while ago I had the same question. It was a bit tricky at that time and
don't know if it's made any easier now.
The problem is that you can always create your own instance of the Action,
but this is not the ideal solution.
Ideally you would like to use the instance cached by the ActionServlet.
Here is how we solved this problem.
1- Derive from the ActionServlet and create this method:
public Action getAction(ActionMapping mapping, HttpServletRequest
request)
{
return processActionCreate(mapping, request);
}
You have to do this because the processActionCreate is protected in
ActionServlet.
2- In struts-config.xml, you need to have a mapping that maps to the action
you want to delegate to. Then the following code should work in your Action:
//Find the mapping
ActionMapping aMapping = getServlet().findMapping("/" + match);
//Retrieve the action instance, associated with the actionmapping
Action delegate = ((MyServletClass)getServlet()).getAction(aMapping,
request);
//This will return an ActionForward
return delegate.perform(aMapping, form, request, response);
If you don't have or don't want to have a mapping for your delegate action
in struts-config.xml, then you can directly access the actions cache in your
servlet like it is done in processActionCreate()
Hope this helps,
Fr.

Thanks
