Hi everybody! I'm a software developer working in a Java card Project, but I'm completely new in the JavaCard environment. I need some help to solve a pair of problems that got me stuck. First of all, I found some sample programs that I am following (javacard kit 2.2.2). Particulary, I'm trying to run the Purse RMI example. I've built the Javacard applets without problems and run a simulation on JCWDE. Now I understand something about APDU commands. But, in the Client side I found a problem. There are some "import" statements that my Java IDE doesn't find.
In particular ( Red ball msg: "com.sun.javacard.clientlib does not exist"):
import com.sun.javacard.clientlib.*;
import com.sun.javacard.rmiclientlib.*;
Please, let me know if I need any additional Tool or library to install.
I am using:
- java_card_kit-2_2_2
- IDE: Eclipse (with plugins) and NetBeans (6.9.1)
- jdk1.5.0_16

Thanks in advance.
