Getting hold of the servlet context within a filter

Question

How can I get hold of the servlet context from within a filter?

Answer 1

The Filter has a FilterConfig that contains the ServletContext.
class myFilter implements Filter {
   private FilterConfig config;
  public void init(FilterConfig filterConfig)
          throws ServletException {
        this.config = FilterConfig;
    public void doFilter(ServletRequest request,
                     ServletResponse response,
                     FilterChain chain)
              throws java.io.IOException,
                     ServletException {
          ServletContext context = this.config.getServletContext();
}
