Hi Marc,
the CardRequest-object is not "senseless". The CardRequest-object specifies
the CardService which is required for the purposes of the application. For
one card there can be many available CardServices. For instance
FileAccessCardService or SignatureCardService.
If a card is inserted, the ATR is passed to all CardServiceFactories that
are registered in the opencard.properties file. Now the factory has to
decide if the ATR specifies an available cardtype and if for this cardtype
the required CardService is available. If the card doesn't match your
requirements you can't use it for the purposes of your application and need
not to create a SmartCard object.
Nevertheless I'm also not completely happy with the current mechanism. In
my oppinion it would be helpful in some cases if I could ask for an
Enumeration of available CardServices for an inserted CardType.
Kind regards
Gunnar
