I am extending HttpSessionStore and keeping track of my sessions there. I am
able to get a hold of members of my Session while it is being invalidated. I
am not quite sure what you mean by " on the unBind() / onDestroy the actual
session object does not exist anymore", the session seems to be available
and I am able to access members of it as long as I store the Session in
onBind(...). This is what I am doing:
public class ScanManSessionStore extends HttpSessionStore
{
...
private Map<String, Session> sessions = new ConcurrentHashMap();
private Map<String, Device> devices = new ConcurrentHashMap();
protected void onBind(Request request, Session newSession)
{
sessions.put(newSession.getId(), newSession);
}
protected void onUnbind(String sessionId)
{
if(sessions.containsKey(sessionId))
{
Device device =
((ScanManSession)sessions.get(sessionId)).getDevice();
if(device != null)
{
devices.remove(device.getDeviceId());
}
sessions.remove(sessionId);
}
}
...
}
Please let me know if there is a problem doing it this way.
