Hi,

I would like to obtain a list of sessions. Old way was to look at
HttpSessionContext, however that is deprecated.

Would be great if someone can share an example of how I would
accomplish this!

Cheers,
Theo

Hi Theo,

Use HttpSessionActivationListener as follows for your requirement,

<<

class SessionCounterListener implements HttpSessionActivationListener
{

public static final Map activeSessions = HashMap<String,
HttpSession>();

public void sessionDidActivate(HttpSessionEvent event) {
HttpSession session = event.getSession();
activeSessions.put(session.getId(), session);
}

public void sessionWillPassivate(HttpSessionEvent event) {
HttpSession session = event.getSession();
activeSessions.remove(session.getId();
}

}

>>

Define the above listener in web.xml as,
<listener>
<listener-class>my.package.SessionCounterListener</listener-class>
</listener>

Use below code to get the active sessions,

SessionCounterListener.activeSessions.size() - Returns the number of
active sessions.
SessionCounterListener.activeSessions.getValues() - Returns the all
the active sessions.

Regards,
Bala.

.... and don't forget proper synchronization.
