Access restriction on sun.security.pkcs11.SunPKCS11
I'm trying to setup a PKCS11 provider for accessing a smartcard. I installed a PKCS11 library on my system and followed the instructions in the Java PKCS#11 Reference Guide. In the reference they simply create an instance of sun.security.pkcs11.SunPKCS11 and pass the name of the configuration file to the constructor. When I try to compile the following code
Provider p = new sun.security.pkcs11.SunPKCS11("pkcs11.cfg");
Security.addProvider(p);
I get the following error.
Access restriction: The constructor SunPKCS11(String) is not accessible due to restriction on required library /usr/lib/jvm/java-6-sun-1.6.0.24/jre/lib/ext/sunpkcs11.jar
What am I doing wrong? I use Eclipse 3.5 with Java SE 1.6 under Ubuntu x86.
Best regards.
Look into the projects's properties and open the Libraries tab. I assume you have set the JRE System Library to an execution environment. Change it to the workspace JRE or select a specific JRE manually.
Background: By selecting an execution environment you say that you want to write an app that is compliant to the Java API. The class sun.security.pkcs11.SunPKCS11 is located in the sun package which marks it as proprietary to Sun Java implementation and is not part of the standard Java API.
Go to your project properties, Java Build Path pane, and expand the JRE System Library entry. Click Access rules and click the Edit... button. Add an Access Rule that makes Accessible the Rule Pattern sun/security/pkcs11/** . This will make Eclipse stop whining.
There is one other cause if you use a 64 bit runtime on Windows . In that case, the necessary classes are simply not present.
Solution: Use a 32 bit runtime.
