Methods

Modifier and Type	Method and Description
void	close() This implementation does nothing: We're dealing with an externally managed DataSource.
void	closeConnection(java.sql.Connection con) This implementation simply calls Connection.close.
void	configure(java.util.Properties props)
java.sql.Connection	getConnection() This implementation delegates to the underlying DataSource.
javax.sql.DataSource	getDataSource() Return the DataSource that this ConnectionProvider wraps.
protected javax.sql.DataSource	getDataSourceToUse(javax.sql.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.
