You're probably better off setting up a Hibernate listener if you want
to do audit logging. Check out the Java Persistence with Hibernate

Well, Wicket is an unmanaged framework, so you're going to have a hard
time getting it to use spring to instantiate and inject beans for you.
However, you can move this proxy creation logic up into a superclass
if you wish:
public class BasePage extends WebPage
{
protected Object
.)... and tell spring if any wicket bean comes into then
handle it in a special way.
Are there any other options ???

one thing you can do is use wicket with guice and hibernate, and have
warp-persist ( http://www.wideplay.com/guicewebextensions2 ) for
transactions.
it's a nice stack that i use, a lightweight alternative to spring. and
no need for java ee containers.

And yes, you should be able to run Wicket in an EJB3 Container, but you'll

Hi everyone,
I have been reading wicket in action recently and I have seen pitfalls of
hibernate section.
I was wondering about the stuff about hibernate and memory leaks due to
hibernate proxy objects maintaining a reference to the session with them
Am I doing this wrong then?
@SpringBean
I think the memleak will not occur that easily because i believe
hibernate removes the session from each proxy / persistent bag after
it is closed. But you really should use the LDM (or another sort of
lazy loading model) because it will prevent a lot of
lazyinitexceptions and other hibernate
Yes I think you are right. By using the LoadableDetachableModel you prevent
the List to be put in the session.
