SystemSession question

[Esteban Franqueiro <ef...@bea.com>]

Hi all.
We want our component to be notified of every property event, and we
were thinking about using the system sessions to connect the listeners.
The idea is to install the listeners on repository startup, with the
system sessions so that we don't miss any possible event.
Is there any significant performace issue related to using them in such
a way? Is it advisable? Is there a better way?
Regards,

no, there is no performance impact. event listeners are informed using a 
background thread.

I would rather use a regular session, which has read access to the whole 
repository. The system session is jackrabbit internal and should not be used 
unless there is a very good reason.
