Hello all,



I'm starting to implement the GP on a Java Card. I've studied the 'GP spec 2.1.1' and the 'Implementation requirements' from the GP website, but it still makes me confused.

Now, I have several questions.



1. Which one has the system's main function, OPEN? or JCRE?




2. Here is one package with four applets.
packageA [applet1, applet2, applet3, applet4]


2.1 Can I load only applet1 and applet2 to the JavaCard?

2.2 If the applet1 and the applet2 are already in the GlobalPlatform Registry with the package A , then can I load the applet 3 and the applet4 with the package A to the card?

The Install[for load] command check the package A's AID, so I think I can't do the 2.2, but I'd like to make sure.



3. All applications SHOULD get the CVM verification? I'd like to know if it is mandatory for applications.

3.1 I think the CVM handler will process all CVM service, then do I have to develop the CVM handler?




Thanks a lot,

Julie.
