Java Card

Greetings,

I need some urgent help with the following:

I have a JCOP card which runs an Muscle applet that makes card act as a cryptotoken. I have managed to write certificates on the card for authentification to web sites(SSL9 and web services. When I sucessfully login into secure web site(https),browser should send the java applet back to the client.

This java applet has a simple task of writing some file to the smart card(that contains certificates and some file). It should use PKCS#11 provider installed on the client. I have managed to write the certificates and files with openssl on the card,but need to do the same with the java applet that downloads on the client. Can I do that with Java applet and how???

please help,Im desperate, I have tried using many solutons with achieving that,but with no sucess.I cant use windows based solution(dot net) becouse MS CSP doesnt support this pkcs#11 provider(opensc dll).
