Thanks for all your answers, it definitely helps me a lot.
Felix, your point is good.
I cannot use the HTTP session since several HTTP requests can occur at
the same time for a single user (because of AJAX), that would not be
thread safe.
One more question: Is there a way to check if there is no more open
session on a repository? I would need that to write a test that ensures
no session remains open at the end of my use cases.

John

Hi,
Over in Apache Sling, we create new sessions for each request.
We used to have Session pooling (maintain a pool of open sessions per
user to be reused on future requests). But this proved unstable and
slower than calling Repository.login on each request (!) and we will
remove the Session pool code in the near future.
We do not use any HTTP Session. Also we do not share sessions between
requests. The problem, you will have doing this is, that Session objects
are not thread safe.
So while reading from the same session concurrently will generally be
rather safe (no guarantee, though), writing concurrently with the same
sessions is a guaranteed failure.
Hope this helps.
Regards
Felix

Hi everybody,
I would like to have advices about how I should handle JCR sessions in
my application context.
I have read the guide on the wiki, but I'm not clear about what is
called "transient mods", if my application fall into it, and finally how
to deal with that case.
I am using a Jackrabbit repository to handle personal storage space for
users of my web application. I've defined personalized access for each
users, so it's about personalized accounts.
Up to now, I've handled sessions by creating a session for each http
request. But since my application makes use of AJAX to display the tree
view of the personal space of a user, a lot of requests may be launched
in sequence, causing a lot of login/logout...
Would it be a better practice to use a http session scope instead of
request scope, with eventually a TTL after which a session would be closed?
Thanks in advance,
John
