While discussing about ServletContextListener, HFSJSP 2e says that it is used for initializing a DataSource. Is this a good approach? I've seen the DataSource objects are handled by the container itself. What is the best way?
My take on this is that it's a good way to do it because the datasource lookup only happens once. I've seen other code where the lookup happens over and over again which is a waste of resources.
