What does your filter's doFilter impl look like?
Normally, this is implemented as follows:
public void doFilter(ServletRequest request,
ServletResponse response,
FilterChain filterChain)
throws IOException, ServletException {
// Filter inbound processing here
filterChain.doFilter(request, response);
// Filter outbound processing here
}
Note that filterChain.doFilter will call the next filter in the
chain, or the service method of the target servlet if there are no
more filters in the chain.
Therefore, a servlet's service method will execute within the scope
of a filter's doFilter, and *not* after doFilter has returned.
Of course, if your filter's doFilter is implemented such that it
never calls filterChain.doFilter, that would be a problem.
