1.what is the connectionpool in jdbc connection?
2.diffrence between normal jdbc connection and connectionpool jdbc connection?
Connections are 'expensive' objects: i.e. the need quite some resources and
it takes time to build them. You don't want a new connection for every little
database interaction. It is possible to reuse such connections, instead of
closing connections you can store them in a pool, ready for reuse when needed.
There are quite a few connection pool implementations available; see the apache
project for a few fine examples.
kind regards,
