Hi Frank,
I was wandering how I can control/influence the lifetime of my stateless
bean, as I am storing some data in private variables to overcome large
calculation times, so that the next time a web user requests the same data
it's already there (after a fixed time I do refresh it if the same data is
still stored in the private variable).
So in a way I think I need a kind of "static" statefull session bean such
that all clients have the same session bean.
What are your ideas about this ?
