No supported card terminal found error on Linux

[uocnb]

I have a ACR122U-A9 NFC reader with MIFARE card.
Demos work well in Windows, but failed to start in Linux (Ubuntu 15.04 x86_64)

I can execute some command with libnfc. I installed libnfc (from source), a library package provided by ACS.

All demos are failed, the error show as below:

java -cp nfctools-examples.jar org.nfctools.examples.clearcard.ClearCardDemo 
Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar

Is nfctools library support libnfc?
Do you have any solution to make it work on linux (or may be cross-platform: linux, windows, osx)?

P/S: thanks for great java library for NFC.

Well, I found a solution, just install missing package and it work well:

• pcscd a pc/sc daemon service to handle nfc reader events to work with libpcsclite - a ps/sc library for Linux / Mac OSX
• pcsc-tools provide some tools written in perl to debug, monitor events, send raw commands.

As Java is searching libpcsclite.so.1 in wrong directory (e.g: /lib or /usr/lib), so it is needed to append the path of library to help smartcardio find it. The demo run well with some exceptions as following command:
java -Dsun.security.smartcardio.library=/lib/x86_64-linux-gnu/libpcsclite.so.1 -cp .:nfctools-examples.jar org.nfctools.examples.scancard.ScanWholeCardDemo

Sample output from my sample card is:

$ java -Dsun.security.smartcardio.library=/lib/x86_64-linux-gnu/libpcsclite.so.1 -cp .:nfctools-examples.jar org.nfctools.examples.scancard.ScanWholeCardDemo
