public class UpdateAddressesAction
Struts action class used for requests to update the address information for a
customer account. Used for requests to "/UpdateAddresses.do".
The execute method of this class invokes
to process the request and update the information in the database. It also
sets the session attribute "shippingAndTaxesProcessed" to "false", in case
the user has gone part way through the checkout process, since a chnage of
the address may affect the tax and shipping calculations.
