Does JCIDE support executing the script file?
I have completed an applet in JCIDE. Now I write a script file and want to test my applet. Does JCIDE support executing the script file? If yes, how can I use JCIDE to run my script file? If it can't cover my need, could anyone recommend other tools for me ?

How to pass APDU command from one selected instance to another instance?

ps: The java card I am using is Java Card 3.0.4, GP2.1.1.
