Hi,

as far as I can remember, it is not enough that ldd finds the libraries.
Maybe you have to tell the Java interpreter where to find them (I see
you installed libJMuscleCard.so in a place where Java will find it for
sure, what about libpcsclite.so ?). Check JNI docs, please.

I'll be back at my office next week to check this problem, in the
meantime you could just provide the OS type and version you're using,
just in case it might be useful.
