This exception is raised because OCF did not find in the set of
declared CardServices one that 1) knows how to handle files (i.e.,
that implements FileAccessCardService java interface) and 2) which
corresponds to the inserted smartcard (this is decided in what is
called a factory). See the OCF 1.2 Programmer's Guide at:
http://www.opencard.org/docs/pguide/PGuide.html
for more details on this mechanism.
Also, the guide explains how to declare the set of known
CardServices (using property files). If the set is empty, this
exception can only be thrown! :-)

First thing is to know what is the card's family exactly. If it's a
"GPK" 8000, then you will find CardServices to handle files at the
following URL:
http://www.gemplus.fr/developers/technologies/opencard/cardservices/download.html
please download both "Generic" (for file-system features) and "GPK" (to
get the factory that will know how to recognize the card) components.
If it's a memory card, I don't think there are any CardServices
available yet.. In fact one has to use very low-level calls (i.e.,
CardTerminal's "sendTerminalCommand") in order to send commands to
a memory card, then you have to know the specs in order to know
what to send.. I have a sample code from Jean Pascal Riss doing
this. I can send it to you by email in case of interest).
Hope it'll help.
Cheers,
Christophe.
