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

Subject: session listener not listening
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-classcentral.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,

RE: session listener not listening
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!

RE: session listener not 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).

2 Problems with Session Listener
Hello, I am using Tomcat 4.1.18 and JDK 1.4.1 I found two problem or bugs: 1) Using Session Listener's sessionDestroyed event I tried to get the session from HttpSessionEvent and log certain information from the session, however this throws an IllegalStateException because the session is already invalid. Reading the servlet API (10.7 page 73), I think it means that sessionDestroyed event should be fired before the session is destroyed. I dunno, might be wrong. 2) Any case, found a work around and I am using HttpSessionAttributeListener's attributeRemoved which mostly works well, except that now I have a new problem. I am calling this.getServletContext() but it it is returning a null if I do it from init and a null pointer exception in GenericServlet if I do it from attributeRemoved. Any one know why? Or better yet, if I can work around it? Thanks, Chanan Braunstein knovel Corp. Web Development Manager 607-648-4770 x672 http://www.knovel.com

Hi, you can create an object that implements HttpSessionBindingListener and store this object in your current session. This object will then be informed when the session gets bound and unbound.

If you are using Tomcat 4, however, you do have an additional option -- you can register application event listeners in the web.xml file that are notified of interesting events (such as session creation and deletion, or changes to session attributes). The /examples webapp has some listener elements to show you how they are registered. Look in the API Javadocs for the following APIs: javax.servlet.ServletContextListener javax.servlet.ServletContextAttributeListener javax.servlet.http.HttpSessionListener javax.servlet.http.HttpSessionActivationListener javax.servlet.http.HttpSessionAttributeListener for the interfaces you must implement.
