Answer 1

DAOs should not be responsible for acquiring a connection to the database. They have no way to know when they're being used as part of a larger transaction. You should be passing the data source or connection instance into the DAO.

If any of the calls to close in your finally block throw an exception, none of the ones that follow will be called. Each one needs to be in its own try/catch block. I put them into a utility class as static methods.
