Re: Business logic goes where in MVC/Struts??

[Adam Levine]

The practice I've done, and seen done, is to call your business logic from 
the action.  Take the form/whatever from the Action, change it into a 
DO/VO/POJO and pass it off.  The business logic can be in a local class, or 
it can call an EJB (stateful/stateless).  This keeps the business logic 
modular and reusable without being locked into a presentation form.
  The business logic can throw errors, populate a List with errors and hand 
it back to the Action.  (Don't forget -- the view layer has some logic: it's 
display logic, not business logic).  The action can then redirect the user 
based on the return (or lack) of errors.

I'm curious where the business logic is supposed to go
when programming MVC/Struts.  In Struts' case it
shouldn't go in Action object right?  Business logic
is considered to be part of Model right?

Bill
