wicket-contrib-javaee: @EJB injection - injecting always the same
instance regardless of session
Hi!
I've just started using the @EJB injection annotation from
wicket-contrib-javaee.
I use it to inject a Stateful Session Bean to keep track of my user
session and do some
stuff like authorization.
I thought the @EJB annotation keeps track of my sessions and would
inject a unique instance of
the Stateful Session Bean for each of my Wicket session.
But, it injects always the same Stateful Session Bean instance
completely ignoring my Wicket sessions. In this case it is useless to
keep track of my users.
Am i doing anything wrong or is this the intended behaviour?
Would it be better to get the Stateful Session Bean by a lookup call and
then store it in the
Wicket session?
Thanks for your help!
Best Regards,
christian

Hi,
At first thought, please try your code out with wicketstuff
javaee-inject, but it will most likely behave just the same.
You cannot store your bean in session, because AFAIK they're not
serializable.
Please rise an issue for this (also quickstart would be great), and I
will look into it.
Best Regards,
Peter Major

Hi.
AFAIK a Wicket user session and a EJB Session are separated. Meaning that
the EJB container decides whether a new EJB instance needs to be created or
not. However even if multiple Wicket sessions get the same EJB instance the
EJB container will still ensure proper synchronisation and transaction
management.
