Question

I'm trying to use a eToken to sign a pdf file using a java application I wrote. I'm using a windows 7 64 bit edition with java 6.0.30.

When I run the application I'm getting an exception saying 

Exception in thread "signer" java.lang.UnsatisfiedLinkError: no j2pkcs11 in java.library.path
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)
    at java.lang.Runtime.loadLibrary0(Runtime.java:823)
    at java.lang.System.loadLibrary(System.java:1028)
    at sun.security.pkcs11.wrapper.PKCS11$1.run(PKCS11.java:88)
    at java.security.AccessController.doPrivileged(Native Method)
    at sun.security.pkcs11.wrapper.PKCS11.<clinit>(PKCS11.java:86)
    at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:281)
    at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:90)
    at com.greytip.cougar.pdfsigner.PdfSigner.getProvider(PdfSigner.java:364)

But when I looked up the j2pkcs11.dll file is available to jdk 1.5 but not available in my jdk 1.6 64 bit.

Is to anything to do with java security policy since the exception is coming inside AccessController, ie the dll is inside a protected directory inside windows 7?

Thanks in advance.

Was it helpful?

Solution

It looks like pkcs11 is not implemented in any of the 64-bit versions of java. It is only available in the 32-bit version.

So I'm planning to install a 32-bit version of java and work with it.

OTHER TIPS

I Had similar issue and tested signing code on jre-8u31-windows-x64 and had success. So i suggest to use this java version. In my scenario I had to sign an xml file which is around 196MB in size for a government application called e-defter. To sign this file java needs memory (HEAP) at around 3GB. I could get this memory with 64 bit java.
