This is the correct approach. However, if you are using struts and the
action is set to redirect="true", the request will never make it to the
JSP and you'd have to use the session. Unless you are changing the
model in your servlet (i.e. processing a POST), there is no reason to
use redirect.

The
problem was when the JSP receives the request and does a getAttribute
on the request it is saying the ArrayList is null.

Make sure you are using the correct attribute name - it is case
sensitive.
