I am using JCOP tool so load it in java card.It is successfully loaded in the card but when I am sending command on it, Select APPLET is giving 9000 but other command gives;

jcshell: Error code: -7fefffd1 (0x8010002F)
jcshell: Command failed: SCardTransmit(): 0x8010002f, PCSC failed with 0x8010002F: 0x2F (Warning,--,(SCard))

and When I am using Gpshell , I am getting error like:

send_APDU() returns 0x8010002F (A communications error with the smart card has been detected. Retry the operation. 

In debug Mode , all result is coming good. Could anybody tell me where i am doing mistake???

I found in ISO7816-3 , "Sw1 =60 is a NULL Byte, it request no action on data transfer" . this was the cause of communication error.. when i tried for 9000 , same code works good in simulator and real card...thanks for all
