Hi Jerry,

Without knowing barely anything anything about J2ME, I can at least say 
that using regular java you only need a JCE provider (standard java api) 
for your smartcard to get it working nicely with bouncycastle. 
Bouncycastle classes almost always have a method that takes the name of 
the signature provider as an argument.
So in this case you have to implement/override the JCE provider API to 
make signatures with your card.

Cheers,
Tomas
