EXP loading on card

Hi,

is there any possibility to load additional exp files on-card (e.g. BIO API exp of stub files). And is there any possibility to load additional packages (e.g. for work with TLV structures, an not to parse them by myself on-card) from Java Card newest version?

Thanks for the help.

Best regards,

Eve

No, export files are never loaded into the card.

They are only used off-card by the converter to map Java {class|method|field} names to tokens, i.e. to byte values.

ad 2)

If you have these packages (their cap files, no dummies, i.e. the real implementation) and they do NOT depend on some native implementation then you can load them as library package and use them from your applets.

I would expect that any card vendor implementation of a TLV API uses native (C++, C or Assembly language) implementation elements to tune up operations performance. So this is another no-go.

Whatever Java Card does not offer you can implement yourself as a library. So for instance you can take the JC2.2.2 TLV definition and implement it as a library your applet uses on a JC2.2.1 card. As lionking pointed out it might not have a very good performance.

Thanks for your answers.I see the point: the best choice is to use what you have at the moment.:)We'll have to wait for Java Card 2.2.2 implementation, i suppose.:)Thanks a lot.Best regards,Eve
