[Globalplatform-developers] Java card, JCRE and JCRMI

[גל ב. <gal...@gm...>]

Hello everyone,

I'm not sure if this is the right spot to ask to following question. If not
it will be awesome if someone can redirect me to other mailing list or
forum.

AFAIK, most if not all of the UICC are Java cards. Therefore, it has JCRE
and JCVM.

According to the Oracle's Java Card Platform Specification it is possible
to invoke methods remotely using the INVOKE APDU if the applet has a remote
interface.

But I read (I'm sorry I don't remember where) that the JCRE can invoke any
method of the Java card API of any applet.

So my questions are :

   - Is it right? Can the JCRE invoke any method (in the API) of any applet
   (even if the applet doesn't implements the RMI interface) with the INVOKE
   APDU?
      - If it can't invoke those methods with the INVOKE APDU, can it
      invoke the methods with other APDU?
   - How can I send an APDU to the JCRE directly and not to the selected
   application?
   - Can someone please give me an example of the INVOKE APDU?

Thanks for the responders! :)
