According to JDBC Javadoc, a DataSource is a factory for connections to the physical data source that this DataSource object represents.
An object that implements the DataSource interface will typically be registered with a naming service based on the JavaTM Naming and Directory (JNDI) API.
Example: {{{
DataSource ds = (DataSource)ic.lookup("java:/DefaultDS");
Connection conn = ds.getConnection();
....
conn.close();
}}}
