Handle Hibernate transaction in wicket
Hello,
I'm searching for a best practice to integrate some hibernate
transaction with Wicket. I'd like to implement the "session-per-request"
that is described here
http://www.hibernate.org/hib_docs/v3/reference/fr/html_single/#tutorial-firstapp-workingpersistence
I think I can commit the transaction and close the session on the
"onAfterRender" method. But where is the best place to start it? On the
first line of the constructor? Or in the onBeforeRender (I think not)?
Anywhere else?
And what about the ajax queries? I need to recreate a new transaction
for each ajax request, need I?
Thank you a lot for your think :)

It sounds like you're looking for "transaction-per-request" and not
"session-per-request." The "session-per-request" part is easy. Just
use the OpenSessionInViewFilter from Spring (as stated by someone else
on this thread). The OpenSessionInViewFilter doesn't begin a
transaction for you automatically. It merely opens the session and
closes it for you.

Actually, Spring lets you (more importantly them) not worry about the
transaction stuff at all. The person (you, perhaps) who is wiring
things together can add in the transaction stuff in the XML file.

Yes, I read a bit about Spring some time ago, but atm I'm working on a
project that will be released soon. I can't afford to rewrite half my
code on the lasts weeks ;)
Next time, I'll take some time to getting started with it. I'm sure it's
worth, that's what I read all the day. But I must consider my
colleagues, too... They are not very very interested with dev, and
already have difficulties to write php... so, with Spring, they will
shot themselves :)
Thx

Once you get used to Spring, you'll really appreciate it. I wouldn't
write it off as too difficult if I were you. It's definitely worth
learning (and it helps your resume; it's in high demand).

Thank you all for your ideas.
At the moment, I handle it manually (transaction and session), and until
now, I don't got much problems.
I don't want to use anything from spring, as it seems a lot more difficult
than anything else in my project.
I've put a closeSession on the onAfterRender method, and every part of my
code that use the DB are properly surrounded with transactions... I don't
have any problem, and even if it is a bit slower than a best practice, it's
enough for me ;)

I use onBeginRequest and onEndRequest from the WebRequestCycle, seems
to work well.
