I wouldn't do anything more than confirm proper data types with validation - required fields are provided and of the right type, etc.
If it is a trivial calculation that isn't used anywhere else, then you could do it in your Action's execute(),
but if it is a reusable calculation like loan payment amount given a principal and number of months, etc., it sounds more like reusable business logic that should be in a model object called by your Action's execute.

Hi,
well i just wonder, in which class i should do my calculations. E.g. : I have a JSP, where i have a form for input values, and output values. Now i can do the math within the validate Method of the according ActionForm, or i do it in the execute Method of the Action where i have access to the form too. Or is there a third way, to do it ?
Esp. whats the best way, if i have to get values from various ActionForms
for my calculations ?
Thanx
