Hi,
The GemXpresso card family are Java Cards, object oriented, and doesn't implements any
file system after gemplus personalization. That's why you cannot read or write files
if you didn't create a file system with an applet or a shared library. In Sun Javacard
2.0, an implementation was specified but removed in Javacard 2.1. No file system is
default implemented because:
- it will no satisfy all users specifications and implementation details
- to keep all the eeprom available for users that didn't need file system or that try
to create an object oriented application.
We can see that a lot of people are using file systems because of native cards, GSM,
and old project porting, but for new applications on Java Cards, manipulating objects
in an applet is more powerfull then reading a file system ;).
The problem of writing CardServices for JavaCards (Signature, key store, etc...) is
that OCF specifications contains a lot of references to the file system. It's dificult
to implements file system oriented interfaces when you have NO file system...
Regards,
Christophe.
