Pieter,
A follow up thought from one of my colleagues -- have you tried using the OCF/PCSC
bridging code ?
This would let you write your high level code in Java whilst maintaining a PCSC
driver at the low level and circumventing the javax.comm issues. You would of
course lose portability but since you have a PnP reader you have done that
already.
Regards
