Hi, all. I would like to know exactly what are the approved/documented ways to get a connection.

My reason for asking this is, I want to understand what all touch points there are in JDBC that allow you to get access to the first implementation class for a given driver. If I have it right, everything hangs off of a Connection, so what are the ways in which you get a Connection?

I know one way is to load the driver class and then use DriverManager.getConnection().

Another way is, in a managed environment, use JNDI or some other mechanism to load a registered DataSource and then use that to get a connection.

Are there other ways? Can, for instance, a user directly create an driver specific DataSource instance (rather than going through JNDI) and then use that to create connections? Or is that not a supported mechanism?

Thanks,

David
