I am trying to implement the execAndWait interceptor along with a custom
authentication interceptor in an interceptor stack that most of my actions
will call. I understand that the action being called needs to implement
sessionAware if it wants to access the session. My question is: what about
other interceptors on the stack...do they also need to implement
sessionAware?
In my example, my authIntercept is accessing the session from the invocation
object. Is this a problem? Should my authIntercept be implementing
sessionAware and getting the session object from there?
Thanks
