Pool Pooling Pool

How can I implement connection pooling in Java?

Is there some kind of template?

I have to use some connections and free them. This connection should be closed a few times.

You can use some libraries. For a JDBC connection pool, check bonecp , c3p0, or dbcp . If you need a shared pool, see the shared pool that dbcp has built.
