What about the structure of the files in ISO/IEC-7816, this concept is not in jcard.

Hi all

I've read about ISO 7816-4 and he talk about MF, DF, EF files which are used in smart cards, I use the java card.
I'm reading java card but I have not read about the structure of these files,
According to iso/iec-7816-4, A4 is an INS to SELECT a command FILE. In scosta if I want to record the name of the smart card then I do

* 1 *-create MF
* 2 *-create Df (INS - E0)

* 3 *-create ef with record structure(INS-E0) oriented

* 4 * run the command "write" record (* INS-D2 *)
and now I can read this name when I want it using the read record command.
-------------------------------------------------------------------------------------

I just want to know that if I want to record several names in java card (in java card eeprom) so what line I need to write within the PROCESS of the applet () method.
-Permanent how to record in the smart card memory?
-How I read the perticular data or the location where name exists?

Thanks in advance...
