load jpcsc library fails

[Guy Van Iseghem]

Hi All,

I have an urgent question.
I'm currently using the jpcsc library(from IBM) needed to communicate with a smartcard. Although when I execute the following line
Runtime.getRuntime().loadLibrary(PCSC.pcscNativeLibName);

gives the exception:
java.lang.UnsatisfiedLinkError: no jpcsc in java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)

Please does anyone knows how I could solve this problem?

Thanks in advance!

This line in the exception tells the whole story:

java.lang.UnsatisfiedLinkError: no jpcsc in java.library.path  

The system is trying to load a library named jpcsc, presumably one that the smart card reader uses, and it cannot be found. Locate it and set the system property java.library.path to point to the directory where it resides.
