I am writing my master's thesis which is concerning Java Mobile and Java Card. I am developing a smart card applet on a SIM card. I planned to comunicate with this applet using JCRMI, but I have just realised the are no devices supporting this package. Browsing this forum I have discovered some terminals support Satsa-APDU which can be used instead. I have some questions and I hoped you could help me:
1) Could you exactly tell me which devices support the satsa-apdu? (In specs jsr 177 is generally mentioned but I would like to be sure it's not only crypto and pki)
2) If I would like to connect (using satsa-apdu) from my Java app to the applet I am developing on the SIM - do I need any signing and so on?
3) If I really need to sign the midlet to communicate by apdu with the applet loaded on the SIM - how should I do it?
Thanks in advance for you support.
