Question

2- I can write a simple javacard applet in Eclipse with JCOP , But how can i write Sim Toolkit applet in there?
3- When i want to add Sim.Jar Library in javacard Project , Eclipse just throw an exception.

Answer 1

Javacard applet vs SIM toolkit applet
The SIM toolkit applet is also Javacard applet. However, it uses the APIs from sim.toolkit and sim.access according to 3GPP TS 43.019 or related specs. Instead of using process() as the main entry, the SIM toolkit main entry is processToolkit() .

Write SIM Toolkit applet in JCOP
You can write it using JCOP or plain Eclipse by adding the required JARs/libraries.

Exception on SIM.JAR library
Please post your configuration and the exception thrown.
