Re: [aspectj-users] Passing in parameters from runtime code

[Jonathan Amir <jamir@xxxxxxxxxxxxxx>]

Depending on what web server you use, it might provide you with hooks to 
the creation of new sessions. What I mean to say is that it might 
provide some listener interface, so whenever a session is created, the 
interested listeners are notified.

I am guessing that if your aspect (or a helper class) will implement the 
listener interface, it will be able to access each session object, and 
from their get each of the Subject objects.

One more thing to consider: you'll probably need to change the 
declaration of your aspect so it is no longer a singleton.
