Hello all,
I'm using pcsc-wrapper-2.0, gemplus-gpk-0.3.jar and
gemplus-service-0.3.jar to access MPCOS-EMV. My reader is a ZeitControl
Cybermouse Serial (ACR20S).
I created a dedicated file (:3F00:0300, no access conditions) and a
transparent file (:3F00:0300:0303, 1024 bytes long, no access
conditions) in my card using the GPK Pilot 2.00 tool.
Then, I executed a piece of code based on the write example presented at
the begining of OCF Programmer's Guide, and I verified the results using
GPK Pilot. As expected, the contents of the file was the string I wrote
("This is a test.\nThank you."), followed by zeroes.
However, when I execute another piece of code based on the read example
of OCF PG:
byte[] data = facs.read(file.getPath(), 0, file.getLength());
it returns a byte[] of length around 160, and its contents has nothing
to do with what is in the card. Here is what it prints:
[B@1dfbff[B@750159[B@a7efd[B@6cd7d5[B@439a2d[B@3bad12[B@632c2d[B@60420f[B@540408[B@1a626f[B@65855a[B@1b9fb1[B@7934ad[B@70eed6[B@691f36[B@694e92[B@6b7859[B@30e280
Also, if I try to write other things, it uses the Write Binary command
of the card, which according to MPCOS-EMV manual performs a logic OR
operation between the data already on card and the data being written,
instead of using the Update Binary command, which *replaces* the old
data with the new data.
Does anybody know how to overcome these 2 problems?
Thank you,
Sergio Saad
