Answer 1

SunPKCS11 provider is present only in 32-bit Windows version of JRE up until JRE7. Since JRE8 it is present also in 64-bit Windows version of JRE. This is the information you see in JEP131.

If you need to use PKCS#11 API in 64-bit Windows version of JRE older than JRE8 then you will have to use one of alternative 3rd party implementations - such as IAIK-JCE.

I have also noticed in your code sample that you are trying to directly use "j2pkcs11.dll" as a PKCS#11 library which is wrong because it is just a JNI wrapper sitting between JRE and the library implementing PKCS#11 interface. Instead of loading "j2pkcs11.dll" you need to load PKCS#11 library provided by your smartcard or HSM vendor.
