Subject AW: Get active Sessions from webapp
Date Wed, 16 Jan 2002 06:24:55 GMT
Have a look at Craig's answer:

In a servlet 2.3 environment (Tomcat 4), you can accomplish your goal
without getting into the innards of the container.  Simple create and
register an HttpSessionListener, which will be notified every time a
session within your app is created or destroyed -- it's easy to maintain a
local HashMap (or something) of the currently active sessions.

Betreff: Get active Sessions from webapp

Does anyone know if there's a way to get some kind of a reference to all of
the active sessions in a webapp?  I just want to know how many Sessions
there are.
I'd just like to be able to say something like "There are currently X Number
of users online" on some page.
