Hi
I'm assuming when you say that information passed / stored in the
HttpSession will be passed up the wire you mean sent back and forth from the
App server.
I, maybe due to my limited experience, can't see how using references to a
session bean on the client side can reduce network I/O in lieu of just
stuffing (temp)variables into the HTTPSession and processing them when
ready. If I process the 7 form 'wizard', with validatred data from the
forms, and then send it along to my session bean, doesn't this now create
only one big bulk update on the business side instead of 7 little updates?
(Refer MVC, Model 2 / Request dispatcher Pattern and the Struts Project at
Apache.org)
