I guess I could do that by having a flag for that in the action and then
using that in the jsp but really tat doesn't quite answer the question. In
general how do we access the request or session in the jsp?
Will what I have given below work or what shud I be doing to make it work!
Is it that I have to implement the sessionaware and requestaware interfaces
in the action to be accessing the session and request in jsp? I am already
doing this and am getting the session object in the action? Will the request
and session available in the jsp as shown in my code below only if the above
interfaces are implemented by the action class? The requirement is tat I
need to access it in the jsp and not in the action class method.
