JavaCard OS

I have a program that sends APDU command to applet in JavaCard and receives result APDU command from Java card. Now I need to give one time PIN when I use this program.But how can I do "Cached PIN" in java card? Any help?

Are you sure you want to do One time PIN?
"One time PIN" sounds like you are talking about an OTP (one time password). Generating these is a complex problem.
