Hi!
The rule is:
Close any object that refer or use something remote (connections,
statements, resultsets) as soon as possible. Because this kind of object
are not automatically garbage collected and will remaind until you
explecitly close them.
The exception is:
if this kind of object are pooled then never close them explicitly just
release them back to the pool ( sometimes the method to release the
object to the pool is called ".close()" but it dont explicitly close the
object. It still juts give it back to the pool). The pool is reponsable
to decide if it need more objects and create them or have to much (or to
old objects?) and decide to destroy/close them.
Regards.
