I don't think I can do this because they may come from a number of 
pages.

You can specify a dynamic ActionForward return in your Action class
execute(...) method.  Not sure why this presents any difficulty at
all.

My apologies for not reading first - yeah - use a dynamic one like 
jack said.  I would PROBABLY subclass Action with an abstract subclass 
- something like:

Hello again,
I've found this interesting and seemingly useful piece of information in 
a struts book I recently obtained. 

Dynamic Forwards
ActionForward forward = new ActionForward("/do/itemEdit?action=edit");
Then it goes on to tell me to use the runtime parameter techniques in 
the previous sections to help build my ActionForward path.  There are 
two techniques:

Adding parameters in the page
or
Adding parameters in the Action class:
ActionForward forward = mapping.findForward("article");
StringBuffer path = new StringBuffer(forward.getPath());
boolean isQuery = (path.indexOf("?")>=0);
if (isQuery)
      path.append("&amp;dispatch=view");
else
      path.append("?dispatch=view"0;
return new ActionForward(path.toString());
Ok, so having that found out... and with what you've given me from above 
can I do something like this?

::regular class stuff::
String previouspath = request.getSession(forward.getPath());
ActionForward forward = new ActionForward(previouspath);
::regular class end::
I'm going to try it out... if anyone sees me doing some really bad stuff 
feel free to slap my wrists :-P.
