Forgive a possibly stupid question, but how would a class know whether
there is a Connection for this thread already? I use a simple static
to hold the Connection, and so I get one for the whole program. But
there is a lot of asynchronous stuff going on with GUI callbacks,
external "messages" and RMI calls, etc. Do I have to create and
destroy a connection in every callback, or use some sort of thread
pooling system? A previous engineer on this project had one subsystem
that was creating a new database connection every second, and then
closing it a few milliseconds later - that seems like madness to me.
