session listener not listening

[Stephen Charles Huey]

My session listener doesn't seem to be listening. At the top of my
web.xml (before any servlet elements, and I have nothing like a filter
or anything else before it), I have this:

<listener>
<listener-class>central.OurSessionListener</listener-class>
</listener>





Here is my listener class:


package central;

import java.util.HashMap;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;

import wwxchange.utility.*;
import wwxchange.beans.*;

public class OurSessionListener implements HttpSessionListener {

public void sessionCreated(HttpSessionEvent se) {
HttpSession session = se.getSession();
UserAcctBean user = (UserAcctBean)
session.getAttribute("currentuser");
String loginID = user.getLoginID();
System.out.println("Added session: " + session.getId() + " for user
" + user.getLoginID());
SystemControl.addActiveUser(session.getId(), user.getLoginID() );
}

public void sessionDestroyed(HttpSessionEvent se) {
HttpSession session = se.getSession();
SystemControl.removeActiveUser(session.getId());
System.out.println("Removed session: " + session.getId());
}
}


My SystemControl's static HashMap doesn't seem to be getting updated,
and the above methods aren't even getting called because nothing is
going to stdout when I log in as different users.

What am I doing wrong? Is my listener not registered to listen?

Thanks,
Stephen

Hi,
Are you sure that page you are accessing creates a session? ;)

How do I get the user IP address? I only get the IP of the server.

Thanks

HttpServletRequest.getRemoteAddr()

if the users are behind a proxy use the following approach:

String endIp = req.getRemoteAddr();
String endIpfoward = req.getHeader("X-Forwarded-For");
//the user is behind a proxy
if (endIpfoward != null) {
endIp = endIpfoward;
}

so you will get the real ip address anyway, even if it's behind a proxy...

I'm trying to add this session listener to a production site that often
has over 2,000 concurrent users (according to the Tomcat manager app).
As far as I can tell, a session is created as soon as you log in because
the very first JSP is accessing a bunch of session beans. However, my
listener doesn't seem to be listening!

One other thing: most of our web app's Java classes are put into a
single JAR file in JBuilder that we then dump into Tomcat's common\lib
directory. However, we have to put our servlets individually into
Tomcat's common\classes directory. My session listener class gets
compiled into the JAR file with all of the other classes in that central
package (see below), so I was wondering if perhaps this session listener
class needed to be dropped individually into the same place as where the
servlets go, and I've tried that (I've even tried making sure the class
was also dropped into a directory in common\lib\central in case that's
what it needed). However, this still isn't working for me! At least,
sessionCreated and sessionDestroyed never seem to be called, according
to my print statements (and the static methods they call don't seem to
be updating my session HashMap).
