This MIDlet demonstrates communication with a smart card using Application Protocol Data Units (APDUs), small packets of data. APDUMIDlet expects to find two simulated smart cards. You can run the smart card simulator using cref, which is part of the Java Card Development Kit.

The Mohair application includes pre-built memory images that you can use with cref. The memory images contain Java Card applications with which Mohair interacts. The memory images are in the root directory of the Mohair project.

  1. Right-click on the project, select Properties, and choose Running. Enable Regular execution and check Specify the Security Domain. Choose maximum from the list.

  2. Start up two instances of cref, one for each simulated card slot (assuming the current directory is the SDK installation directory):

    start bin\cref -p 9025 -i apps\SATSADemos\demo2.eepromstart bin\cref -p 9026 -i apps\SATSADemos\demo2.eeprom

    Note that the port number arguments (9025 and 9026 in this example) must match the SATSA port numbers. Also, make sure you use the correct path to demo2.eeprom.

  3. Once you have the two smart card simulators running, run SATSADemos. Select APDUMIDlet, select the Menu soft key and select Launch (1). Press Go when prompted.
