    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest req = (HttpServletRequest) request;
        if (req.getHeader("Content-Type") == null) {
            HttpServletResponse httpResponse = (HttpServletResponse) response;                
            httpResponse.sendError(HttpServletResponse.SC_BAD_REQUEST,
                   "Required headers not specified in the request");            
        }
        chain.doFilter(request, response);
    }
