[Struts 2] Iterator usage
Hi,
I have one question regarding iterator. I have one simple list that contain three values:
List { id, value, date } and I'm iterating through this list. And I want to show in my list a sum for value for every day at the last row that contain that date, like this:
id value date sum
----------------------------------------------------------
1 10 20.5.2008
2 15 20.5.2008
3 15 20.5.2008 40
4 12 21.5.2008
5 15 21.5.2008 27
6 12 22.5.2008
...
I'm now have done all iterating except this sum column. Do you have any ideas how efficent can I do this ?

I assume 'rearding interator' means the s:iterator tag in a JSP? I doubt
there is any clean/sane way to do this from within the JSP. Instead, do
the summation logic in the action and give the JSP a data structure that
already includes this information.
