Hi,
I believe that this 'name can't b null exception is because the win32dll is not
being properly located by its JNI wrapper.that class is internally called by the
function Smartcard.start(). so if u externally initialize the CommDriver and
proceed it'll allow u to work. this time also it throws an exception but that
can b ignored...
For the solution u can look back into the previous mails of this list...
For more info on this issue u can look into the java discussion forums of sun.
Regards
Haripriya
