Java - how to detect smartcard hotplug

Question

I load dynamically pkcs11 security Provider in java and it works as long as the smart card reader is inserted before running the application. Could anyone please tell me how

Answer 1

Can you use the javax.smartcardio.* API in conjunction with PKCS #11?

The CardTerminal class has isCardPresent(), waitForCardPresent(timeout), and waitForCardAbsent(timeout) methods which can be used in a seperate thread to poll for card insertion events.

Answer 2

PKCS#11 doesn't define a standard way to actively notify the application about device insertion/removal. The best you can do is to run a thread which will check the number of slots and their state once a second or so.
