Hi Laurie
I had used Request.dispatcher before but only in servlet code; didnt know/realize I \
could do it in an Action.  I see the key is to make that one of the states that will \
always be called and just trick Struts with the return of the null.  I assume the \
technology is orthogonal enough that if I have a browser page, or open a url to the \
Action it will be automatically be "fed" the output of the Request.dispatcher from \
the servlet.  That would be very elegant.

need the servlet? You could  generate the full response from the action. If you still \
need to keep  the servlet around for other uses, perhaps you can refactor the bulk of \
 its work into a service class that both the servlet and the action can 
use to generate the response.

Failing that, the way to do this is to manually dispatch to the servlet 
(using request.getDispatcher("/servlet/path").forward() or something 
like that; I forget the exact API). Then be sure to return 'null' from 
your action to tell Struts it shouldn't do anything further with the 
response.

HTH,
