Ok here's how I did to finally fix it :

* create a new Transient Object Container (sessionTOC) at root
* create a new Session Data Manager (sessionDM), with the following settings :
** Id : sessionDM
** Transient Object Container Path : /sessionTOC
** Place SESSION in REQUEST object as : ZODBSESSION

Now I can put ZODB objects in ZODBSESSION using something like : 

context.REQUEST.ZODBSESSION.set("object",o)

Thanks to all of you for your precious help.
