Re: [Wicket-user] beginners question: wicket and sessions
HI Joahn,
Hi Igor,
thx very much - emm, you dont how EJB sessions are working
with wicket ? (do i have to tie the specific stateful bean to the session or
does the container remember itself the bean to the session e.g.for a shopping
cart...)
Korbinian
PS: you really should change the name from dirty() to
snyc() or sth like that or even go a step further and use AOP to call this
automatically whenever sth is touched

beginners question: wicket and sessions
wicket's session object is stored inside http session. the getters
and setters there are to make your code cleaner then using http session's
map:object-object which is pretty ugly - so instead you use typesafe
getters and setters. and as johan pointed out whenever you modify wicket's
session object you have to call dirty() on it - this call triggers replication
so the session is updated across the cluster if you have one.

http session object so that it knows that the session object is

Hi,
i have a small problem in understanding
the way sessions are used in wicket. Whenever i access any new wicket app
(even HelloWorld) it gives me a SID, so i know i have a (http servlet)
session. However, using the http.session is not the wicket way, and the
wiki just tells:
Custom Sessions
The wicket way of storing objects in your session is by extending
the wicket session. For example if you want to store some kind of user
object in your session, you would create a getter and setter for it in
your custom wicket session: public class MySession extends WebSession { public MySession(WebApplication application) { super(application); } private String myAttribute; // ... getters and setters
}But why do i have to explicitly do the getters and setters for each thing i want to have remembered?? -or did i get sth. wrong here???
Best Regards,KorbinianPS: a little bit off-topic, but im also working myself into ejb3 a bit and i wondered, if i have a stateful sessionBean (e.g. a ShoppingCart) and i call the bean in any wicket page and set a product into it,
how will be remembered to what session the Cart is attached to? - do i have to keep the connection to the specific bean open all the time or does the beancontainer take care for that ???

store the stub in wicket's session object and thats how you reference
it. so instead of stuffing it into httpsession you stuff it into
wicket's. vincent wrote an ejb3 wicket app so maybe he can give you more input or you can woogle [1] for ejb3

aop sounds nice, if there was an intercepor for change to any field value in any object in this instance we might consider it. we are not aop wizs so maybe there is one and we dont know about it.

sure
i can do this... i just meant u usuallydont think about snycronising
whenseeing a dirty() - called functioni think dirty() is quiet standard. it tells the object that you changed it and now it needs to do whatever it needs to do to react to that.

im
neither,but you could
call it everytime a page is processed?yes we could, but that would cause a ton of unnecessary replications and take away a lot of bandwidth inside the cluster.
