Abstract the HashMap behind another class that has a getTotal(Item
key) method, and do the math in there (return item.prize * quantity).
Doing any math in the JSP feels dirty.

so, to know the total for each item i've to multplay item.prize with
quantity.
no more else.

Then why are you re-computing it in the JSP?
The point is only that floating-point math is inaccurate. If you
don't
care, or are controlling the results of the math somehow, then fine.
