Example: Tracking Number of Concurrent Users
Implement the
HttpSessionListener
interface:
sessionCreated()
sessionDestroyed()
A
ConcurrentUserTracker
class that implements
HttpSessionListener
.
A
DisplayUsers
servlet that uses
ConcurrentUserTracker
.
http://redrock.d.umn.edu:8081/jspbook/DisplayUsers
