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?
Any suggestions welcomed, and thanks in advance for
your input.
Martie
