Re: Where should I connect to the database?

Dino-

It depends on the nature of your application:

If you expect to have many copies of the application running (like in a
servlet app), you'll want to release the resource (connection), otherwise
you'll have a lot of processes idling out there when they aren't needed &
may bump into other resource limits. The drawback is that it takes time to
re-establish a connection each time you need it.
As some of the other folks mentioned, using a connection pool would be the
best approach in this circumstance.

If you don't expect to have many copies of the app running, you might as
well leave the connection open & get better performance by having the
connection always ready.
