Should I close a connection that came from a datasource?

When I do a dataSource.getConnection(), when I want the connection to be return to the pool (and not closed), does calling the close method return开发者_StackOverflow社区 the connection to the pool or actually close it?

When you call the close() on connection returned by a DataSource, it would return that to the pool to be used by other thread. Closing the connection defeats the purpose of the pool.
