Web Applett的Java的MSCAPI错误？

Question

I am developing an application that uses Java's Crytographic Extension, more specifically MSCAPI, to sign a file using a user's private key all from a web browser. I have been able to do this succesfully locally, but when i embed the class in a web page and try to access users keystore i get the following error: "no such provider: SunMSCAPI". Does anyone have any knowledge pertaining to the cause of this error?

The line of code that causes the error:

KeyStore ks = KeyStore.getInstance("Windows-MY", "SunMSCAPI");

Thanks

到目前为止，SunMSCAPI仅在Java 6中可用。
