How can I get the HTTP status code out of a ServletResponse in a ServletFilter?

Question

I\'m trying to report on every HTTP status code returned from my webapp. However the status code does not appear to be accessible via the ServletResponse, or even if I cast

One thing missing from David's answer above is that you should also override the other form of sendError:

@Override
public void sendError(int sc, String msg) throws IOException {
    httpStatus = sc;
    super.sendError(sc, msg);
}
