Hi all.
It's a general question, just for the sake of curiosity:
..NET introduced ViewState as a way to keep the state across postbacks. I
love it, use it all the time, blah blah...
But Java has been around for much longer than .NET. I don't have experience
with it. Does Java have anything like ViewState? How do those guys keep the
state? I mean, of course you can create your own session and store it in db
or use cookies, but is there any "stand alone" object / mechanism in Java?
Thanks,
Kikoz

The viewstate just uses and hidden HTML form field. You could do the same
with Java (or more precisely with whatever Java uses to built an HTML UI).
ASP.NET provides a clever server side programming model but behind the scene
it just has to rely on HTML...

Actually, it doesn't have to relay on HTML. .NET just uses HTML hidden field
by default. You can keep ViewState in Application, or Cache, or hard drive.
I was asking if Java has any "out of the box" solution to free you from
developing your own method. Thanks, anyway :)
Anyone with Java background?

We had to spend vasts amount's of time creating/debugging/maintaining a BOAT
load of code to setup a framework and ensure current/new JSPs/servlets use
that framework. :<
In moving to .NET (creating webapps at home :>), there are SOOOOOO many
things C#/.NET just do better/faster/cleaner than the j2ee world. :< The
..NET world gives you and awesome framwork to start off with. In j2ee, you
have the APIs and good freak'n luck! :<
re state
I'm much happier at home with .NET than I was with j2ee! :>
hth :>
I was talking as far as viewstate (client side state) is concerned.
Try : http://java.sun.com/blueprints/qanda...ion_state.html
Java is just a language and all of this applies as well to ASP.NET. Actually
you'll find also the same server side mecanisms such as a httpSession class
etc... Nothing new under the Sun.

I believe that JavaServer Faces technology is a fairly close equivalent to
ASP.NET, and if I remember correctly (I had been working on the J2EE
Tutorial up to a month ago), there _is_ an equivalent to ViewState.

AFAIK how it is implemented is not part of the specification. This is just a
"statebag" that is implemented either server side or client side.
For a client side implementation IMO it's likely it uses an hidden field as
ASP.NET does (easiest way to be able to set something client side and to
have it submitted on the next round trip) and it works regardless of wether
or not cookies are enabled.

hi,
I am studying ASP.NET and have few questions -
1) The session ID and values of controls is stored in VIEWSTATE
variable. So now when we put EnableViewState="false" in Page directive and
disable the session state in Web.Config the VIEWSTATE variable is still
maintained and stores some values. Can anyone tell what those values are
for, i.e what other info is stored in VIEWSTATE other than the session ID
and the control values ?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
