I am having problem in implementing datasource interface, I know all
theoritical details about datasource interface and
connectionpooleddatasource as well but I am having problem in
implementing it I have, i am stuck from where the actuall connection
is returning. I have defined a class RibsDataSource implementing
DataSource interface with getters and setters for properties:

Connection conn;
String serverName serverName;
String databaseName dbName;

And other class PNDatabaseConnection instantiating PNDataSource and
calling its setters, and getting connection by calling getConnection
method, but how does it get the Connection I mean how does
RibsDataSource class creates Connenction object does it do so by
using DriverManager.getConnection()?
