Calling the pcsclite lib on Linux

Question

Hi folks,
I'm trying to access the pcsclite library on an Ubuntu, however without any experiences with C++ programming it seems to be really hard.
Well, I use JNA to access native libraries and on Windows it just works fine, but on Linux I get the error:
Exception in thread "main" java.lang.IllegalArgumentException: Unrecognized calling convention: 1.
This means the methode I tried to call doesn't exist in the library. So I double and even triple checked if I really used the right syntax and if there are no typing errors. Everything looks ok to me.
The documentation of the API defines the method as following:
SCardEstablishContext (DWORD dwScope, LPCVOID pvReserved1, LPCVOID pvReserved2, LPSCARDCONTEXT phContext)
In my main()-Methode the call looks like that:
int pvReserved1 = 0, pvReserved2 = 0;
phContext = new int[1]
int error = winSCard.SCardEstablishContext(libpcsclite.SCARD_SCOPE_SYSTEM,
                    pvReserved1, pvReserved2, phContext);And my libpcsclite interface looks like that:
public interface libpcsclite extends StdCallLibrary{
    public static final int SCARD_SCOPE_USER = 0;
    public static final int SCARD_SCOPE_TERMINAL = 1;
    public static final int SCARD_SCOPE_SYSTEM = 2;
int SCardEstablishContext(int dwScope, int pvReserved1,
               int pvReserved2, int[] phContext);Any ideas what I'm doing wrong? I couldn't find the mistake.

Why don't you just use Java 1.6+ and javax.smartcardio? IMHO this is the "right way" of accessing smart cards on PC/SC level from Java.
