Re: [Springframework-developer] SQLErrorCodesFactory Product Name lookup

Actually, passing in JdbcTemplate would be good enough, as it contains =
its DataSource. JdbcDaoSupport is also implemented that way: You can =
either pass in a DataSource *or* a JdbcTemplate.

I'm still for leaving the example as-is, though: passing in a DataSource =
is more natural, particularly for beginners, as JdbcTemplate remains an =
implementation detail then that's not even visible in configuration.

I think we should make the proposed change, then people can use=20
JdbcTemplate either way. As for the samples, at that point, I personally =

people have to pass in both a DataSource and JdbcTemplate to beans that=20
need it, instead of just a DataSource.
