Maybe this will help.

Bear, that book is a year old already.
What about JSTL 1.1 ?

I got that out of "JSTL in Action" by Shawn Bayern.
But it only covers JSTL 1.0.
Does anybody have a book for JSTL 1.1 ?

Did you try ?
${pageContext.request.remoteUser}

What do you think of "tag files" ? I just started learning how use them. I think that they may be the coolest new feature of JSP 2.0. rick

Daniil, thanks for sharing. rick

It would be nice if you posted your final code here.

Look at this to get started.
http://www.experts-exchange.com/Web/Web_Languages/JSP/Q_20514811.html
Be sure to read Kenneth's final suggestions.

Here are two JSPs that I wrote a while ago. You could use same idea.
------sender.jsp----------------------------------------------
<%@ page import="java.util.*,java.net.*,java.io.*" %> <% Vector vSend = new Vector(); vSend.add("one"); vSend.add("two"); vSend.add("three"); String urlStr = request.getRequestURL().toString(); URL url = new URL(urlStr.substring(0,urlStr.lastIndexOf("/")+1) + "bouncer.jsp"); HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-type", "application/octet-stream"); ObjectOutputStream oos = new ObjectOutputStream(conn.getOutputStream()); oos.writeObject(vSend); oos.flush(); ObjectInputStream in = new ObjectInputStream(conn.getInputStream()); Vector vBack = (Vector)in.readObject(); in.close(); oos.close(); %> vBack=<%=vBack%>
and the second
----------------------bouncer.jsp----------------
<%@ page import="java.net.*,java.io.*" %> <% ObjectInputStream ois = new ObjectInputStream(request.getInputStream()); ObjectOutputStream oos = new ObjectOutputStream(response.getOutputStream()); oos.writeObject(ois.readObject()); oos.flush(); ois.close(); oos.close(); %>

Here is some quick and dirty JSP to demonstrate. Put both files in the same directory.
------------sender.jsp----------------------------------------<%@ page import="java.util.*,java.net.*,java.io.*" %> <% Vector vSend = new Vector(); vSend.add("one"); vSend.add("two"); vSend.add("three"); String urlStr = request.getRequestURL().toString(); URL url = new URL(urlStr.substring(0,urlStr.lastIndexOf("/")+1) + "bouncer.jsp"); HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-type", "application/octet-stream"); ObjectOutputStream oos = new ObjectOutputStream(conn.getOutputStream()); oos.writeObject(vSend); oos.flush(); ObjectInputStream in = new ObjectInputStream(conn.getInputStream()); Vector vBack = (Vector)in.readObject(); in.close(); oos.close(); %> vBack=<%=vBack%>
-------------------------------bouncer.jsp-------------------------- <%@ page import="java.net.*,java.io.*" %> <% ObjectInputStream ois = new ObjectInputStream(request.getInputStream()); ObjectOutputStream oos = new ObjectOutputStream(response.getOutputStream()); oos.writeObject(ois.readObject()); oos.flush(); ois.close(); oos.close(); %>

The first time you request A.jsp, the output is "hello". Refresh it couple times to see different times.

Try this listener. But, please be careful, you will throw a java.lang.StackOverflowError if you let the count go too high. Maybe someone will post code to catch it gracefully.
package pack1; import java.io.*; import java.util.*; import javax.servlet.*; import javax.servlet.http.*; public class RequestTimer implements ServletRequestListener { Hashtable table; public RequestTimer(){ table = new Hashtable(); } public void requestInitialized(ServletRequestEvent sre) { HttpServletRequest request = (HttpServletRequest)sre.getServletRequest(); table.put(request,new Long(System.currentTimeMillis())); } public void requestDestroyed(ServletRequestEvent sre) { HttpServletRequest request = (HttpServletRequest)sre.getServletRequest(); long time = System.currentTimeMillis() - ((Long)table.get(request)).longValue(); table.remove(request); request.getSession().setAttribute("lastRequest",new Long(time)); } }
For testing you could use the following two JSPs.
A.jsp
<% Integer count = (Integer)request.getAttribute("count"); if(count==null){ count = new Integer(0); request.setAttribute("count",count); } if(count.intValue()<=10){ pageContext.forward("B.jsp"); } Long lastRequest = (Long)session.getAttribute("lastRequest"); if(lastRequest!=null){ out.print("Duration of last request in milliseconds " + lastRequest.longValue()); }else{out.print("hello");} %>
and B.jsp
<% Integer count = (Integer)request.getAttribute("count"); request.setAttribute("count",new Integer(count.intValue() + 1)); pageContext.forward("A.jsp"); %>

You could use Praful's code in a Filter.

Of course, I am using windows.
build.xml is in the web app's root directory(in my example "forum" is the context).
Put your source code into src directory and place that into forum directory.

Ok here is mine. I hope to see a lot of others.
