Is the "eToken" the product described here? If so, it's basically a smartcard, which means you can't extract the private key. The way you'd use it is to send the encrypted data to the token and have it decrypt for you.

You said you're using JSP. Are you trying to utilize an eToken plugged into your server, or into the client's PC? A JSP page on your server can't talk to devices plugged into the client's PC; you'd need an application running on the client (maybe a browser plugin) to do it on your behalf.

If it were possible for a website to extract the private key from a user's eToken, the eToken would be worthless as a security product.
