I am new to struts, so I don't know clearly about it. Can anybody explain to
me the roles of struts in an web application?
I saw some versions of struts available at struts home page (e.g. binary,

The controller servlet (ActionServlet) is responsible for identifying the
action form and populating it with data from the request, before calling the
perform() method on your actioin class. So you are correct that the code
from EditRegistrationAction will never execute (why is it there then???).

That proposal would probably work, but it might be a little
