Assuming you can define an interface (like "AccessControlManager")
and instantiate an implementation of the instance at servlet init
time (using ServletContextListener or PlugIn), it should be pretty
straightforward.

Hi,
I have been working on a portal style collection of apps. There is a

As has been noted by others, JMS would be the better solution for an
asynchronous 'process'.
But, if you have to use threads then it is probably a better approach to
create a thread pool at appliction initialization and have the actions use
those threads via a common synchronized data structur

Makes sense,
