Which JDBC resource type to use
Is it true that regardless whehter I use DataSource or ConnectionPoolDataSource as the resource type the connections are pooled?
Is it the case that Glassfish uses its own pooling mechanism if DataSource is specified but can take advantage of the native driver's pooling if ConnectionPoolDataSource is used?
If so, which variant is preferable?
I am a beginner, so a rule of thumb would be enough.
Thanks a lot
