problems with get status code from servlet response

I am trying to create a filter that logs any request for a invalid url.
So in my filter, I need to exam any servlet response to see if it
contains status error code 404. But I couldn't find any methods to
get the content of the response such as status line, seem like
HttpServletResponse class only provides ways to change response instead
of looking into the response.

I suppose you could create an extension of HttpServletResponseWrapper
that overrides sendError methods and lets the filter see what has been set.

Wouldn't it be a better solution to log everything in the 404 page? You
can do that with the error-page element in the web.xml
