Hi Overby
Result is indeed your choice to go.
in general you should avoid any direct use of the Servlet stuff in your
Actions.
you should prepare your data in your action or "execute" then determine what
data type you want to return then return the proper "result" string
then let your Result format the data to what you ie. XML or JSON or even
plain text
this way your Action wont be view-dependent
you can dig into struts' source to find many usable examples on how to do
things in Result
