Yes, of course. Just find out VSDC Visa applet by google, then upload and install this applet into your card.
But you may have to certify the entire package.

Regarding the connection between reader and SAM, it really depends on the implementation.

Moreover, in your structure of FRAME, there must include context_id field like this:

Code: Select all

typedef struct frame {
u1 last_pc;
u2 *lvars;
u2 *ostack;
method_info *mi;
class_info *ci;
struct frame *prev;
u1 context_id;
} Frame;

Context is only an identifier, that is associated with different packages or JCRE.

Its structure may be like this:

context{
u1 context_id
u2 package_addr;
u2 applet_instance_addr;
}

if context is JCRE context, all above entry may be *0xFF*.

Crawford

Well, to do this, you should make your applet default selected when installing your applet.

Just take pyapdutool as an example:
When dialog box "Install" pops up, click on the V mark in the left side of the option "Default Selected"

Thanks for your help! The section you mentioned only defines the structure of the Load File, but not the way of converting .cap file into a sequence of APDUs data block. Use the order for creating a binary blob of data from the cap file and then use the GP LOAD command. A CAP file is a JAR file wit...

Crawford

You can refer to JCVM and GP specification. The JCVM spec defines the order in which the components of the CAP file should be put together and then it is multiple LOAD APDU's to send the data to the card.

Crawford

There is no root applet. Each applet is just packaged in a flat way inside the CAP file as if they were just different classes.

Crawford

I will not suggest this. You can simply ask your vendor about file structure present in your card.

Crawford

As far as I know, the SELECT command will typically cause the currently selected applet to change to an applet with a matching AID.
