Well the following could be done :
At the beginning of your JSP page, retrieve the array from the session
object calling the getAttribute method after that use an if statement to
check whether the array object returned with the above method call is null
or if the size of the array is zero.
If it is stop processing the current jsp page and either forward / redirect
to your other page.
Assume it helps :-).
Have a nice day.

Subject: conditional forwarding from within a jsp page
> In the app I'm working on, there is supposed to be an
> array of objects containing some information that I
> need to display on the jsp. This array is stored in
> the session (an HttpSession). Before using any of the
> objects and their methods, I'm checking to see if the
> array in the session is null or zero length. If so,
> then I don't have the data and shouldn't display the
> page. What is the best way to handle this and display
> an alternate page?
