	To do something like that you need to do it yourself.  i.e. store a
HashTable in the application context, then add and remove sessions to
it when people login and logout, or at some other convinient time.
Of course, this assumes your app isn't running in a distributed environment.
If it is, then it's impossible to get a session object from a different
JVM.  (well, you could serialize it and transfer the data, but it won't
be the same object and it won't be useful for much other than extracting
some info)
