Method Summary

Modifier and Type	Method and Description
void	close() This implementation does nothing: We're dealing with an externally managed DataSource.
void	closeConnection(Connection con) This implementation calls DataSourceUtils.doCloseConnection(java.sql.Connection, javax.sql.DataSource), checking against a SmartDataSource.
void	configure(Properties props)
Connection	getConnection() This implementation delegates to the underlying DataSource.
DataSource	getDataSource() Return the DataSource that this ConnectionProvider wraps.
protected DataSource	getDataSourceToUse(DataSource originalDataSource) Return the DataSource to use for retrieving Connections.
boolean	supportsAggressiveRelease() This implementation returns false: We cannot guarantee to receive the same Connection within a transaction, not even when dealing with a JNDI DataSource.
