Get Action Name from Servlet Request - servlets

Question

I have ABC.action which invokes the doFilter method of Filter Class which is configured properly in web.xml
I need to find action name from request object. How can i achieve this?
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.");
}

Try below code(working in JBOSS).
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();
}
}
