but if I do it in my action class then I am adding extra 'time'.
to begin with I anyways have to iterate over the list in my JSP. Just to
calculate total if I iterate over the list again in java code then I am
doing two iterations through the list. Just didnt seem very efficient for
my need.
Thanks for your suggestion!! :)
