Subject Re: adding values to a variable inside iterator tag
Date Wed, 01 Jul 2009 21:03:57 GMT
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!! :)
