Re-run SunPKCS11 after ProviderException

Question

I am creating an instance of Sun's PKCS11 implementation, but when there are no cardreaders installed on the OS, I get a ProviderException:
From SunPKCS11.java
throw new ProviderException("slotListIndex is " + index + " but token only has " + slots.length + "slots");This is as expected. But when I install the driver for the cardreader, and I want to try again (without restarting the JVM first), I get the same error!
How can I reset any previous errors, without having to restart my Java-application?

Answer 1

I may have misterpreted your problem. When you say
"driver" are you referring to the SunPKCS11 Bridge
Provider, or are you referring to the DLL/SO file
that represents the native operating system drivers
for the PKCS11 token? In pkcs11.config I refer to a generic (safesign) dll, which directs to the omnikey cardreader and a usb token. And the driver I am refering to, is the device-driver, not the generic dll.
The native PKCS11 drivers must always be installed on
the OS before you startup your JVM because the
DLL/SO must be accessible to the JVM when it starts
up. Otherwise, adding/removing the SunPKCS11
Provider in your Java code makes no difference.This means that the generic pkcs11 implementation from safesign (aetpkss1.dll) is already installed, but neither the cardreader nor the usb token has been installed yet, so no slots are found. But then I install the device driver(s) and connect the device(s) and still no slots are found.
So, I guess what you are telling me is that what I want, is impossible in Java?
