Interaction between Webapp and Applet

I know that there is a 99% chance of the answer to this question being "no" due to the nature of Applets, but I'm going to ask anyways.

I have a SmartCard containing X.509 certificates and applets. I'd like to be able to interact between the webapp and one of the applets in a read-only manner to pull data via that applet that is unavailable in the certificate.

Again, I know that applets are supposed to be sandboxed, which should prevent such a thing, but I thought I would ask anyways.

You can use java.net.URLConnection to fire HTTP requests. An applet is allowed to fire HTTP requests on own domain as obtained by Applet#getCodeBase().

URL url = new URL(getCodeBase(), "scriptURL");
URLConnection connection = url.openConnection();
// ...

Substitute "scriptURL" by the path of whatever server side script is listening on the domain, e.g. "script.php", "servletURL", etcetera. You can pass data as request parameters the usual HTTP way.
