I think his point is that his view template is going to iterate these objects
anyways, he just did not include the additional layout html for the
resultsList. I don't think he was suggesting that getting a count by
looping is better done in JSP tags rather than the action class. I am sure
there

Maybe learning about the life cycle of even a simple tag will convince
you that doing unnecessary computation within the display layer is a
mistake:
thanks for your advice.
"...optimizing out a for loop is not the best use of your time as a
developer."
I second that. But in this case why would I write another for loop to do
something that can be done in the for loop that I already have? Unless
there is an issue with doing this inside s:itera
I will bet one dollar that the amount of time it takes to calculate this
value inside your Action class is less than or equal to the time it takes it
to calculate the value inside the iterator in your JSP. And it's a
vanishingly small amount compared to network latency. Unless you're writing
code
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.

I don't know how Struts 2 tags work under the hood, but it's possible that
it's going out of scope because you declared it in the iterator, or it's
silently throwing an error because it isn't initialized. Before your
starts, do .
This could be handled inside your action class with like two lines
oh nevermind.
was experimenting and
works!

Does anyone know how to calculate the total value by making use of the
tag?

for our purpose i'd prefer doing it in the iterator tag.
I tried something like this
but this does not seem to work.
what can fix this?

You're far better off doing it inside the Action class.
That said, you can probably use s:set to get what you want.
