How to display active Session ?

Question

hi,
i would like to implement for an administrative usage, a jsp page that list all active session. I notice in the J2EE api that there's a HttpSessionListener interfaces wich enables listener to receive notification when creating and deleting session. Is it a good way to implement this functionnality, thanks in advance for your help.
PS : i am sure, others persons have already implement a solution, perhaps there is a Design Pattern for that.

Answer 1

Hi ,
Its really simple....
See the following code
public class SessionCounter implements HttpSessionListener {
int sessionCount = 0;
public void sessionCreated(HttpSessionEvent evt) {
sessionCount ++;
evt.getSession().setAttribute("Count", sessionCount);
public void sessionDestroyed(HttpSessionEvent evt) {
sessionCount --;
evt.getSession().setAttribute("Count", sessionCount);
now add this Listener to your web.xml
and you can get it anywhere (in jsp or servlet) using session.getAttribute("Count");
Is this you want.
Please let me know.
cheers
