web.xml で適切に構成された Filter クラスの doFilter メソッドを呼び出す ABC.action があります。

リクエストオブジェクトからアクション名を見つける必要があります。どうすればこれを達成できますか?

public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)
     throws IOException, ServletException {
  long t1 = System.nanoTime();
  filterChain.doFilter(request, response);
  long t2 = System.nanoTime();
  long time = t2 - t1;

  // Just writing statistics to servlet's log
  System.out.println("## " +
        "ArriveTime ns " + t1 + " Departtime ns " + t2 + " ServiceTime : " + time);
//      System.out.println("Time taken to process request to "
   //                                          + ((HttpServletRequest)         request).getRequestURI()
 //                                          + ": " + totalTime + " ms.");
   }

以下のコードを試してください（JBOSSで動作しています）。

    public void doFilter(ServletRequest req, ServletResponse resp,
            FilterChain fc) throws IOException, ServletException {
        System.out.println("Request");
        System.out.println(req);
        // req instance of HttpServletRequest
        if (req instanceof HttpServletRequest) {

            HttpServletRequest httpReq = (HttpServletRequest) req;
            System.out.println(httpReq.getRequestURI());
        } else {
            // req is not instance of HTTPServletRequest then try reflection
            try {
                Class clazz = Class
                        .forName("org.apache.catalina.connector.RequestFacade");
                Method method = clazz.getMethod("getContextPath", new Class[0]);
                String actionName = (String) method.invoke(req, new Object[0]);
                System.out.println(actionName);
            } catch (ClassNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (SecurityException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (NoSuchMethodException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IllegalArgumentException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

    }
