We're talking futures in terms of Struts here, but my question is ... aren't you
doing the Locale-specific conversion a little bit too early?
My thinking is that business logic objects maintain data objects in a
Locale-insensitive format (like java.util.GregorianCalendar or
java.math.BigDecimal). And, the ActionForm properties would be of the same
type. Conversion to or from String would happen at the last minute -- just as
you prepare the page for display, or as you are accepting the input.
Admittedly, we need better support in Struts (such as your formatting version of
<bean:write>, and a way to process the input string with PropertyEditor type
classes) to make this strategy really effective, but I would suggest not doing
the Locale-specific formatting until you have to.
