Yep, straight JDBC would work.
For me, it depends a bit on the urgency and complexity. If this is urgent
and the POJO is simple, just write JDBC. If the POJO is a little more
complex, say holding references to other POJOs or lists, then I'd really
consider moving to a JPA system (of which Hibernate is the one I know).
Like most tools, Hibernate/JPA mapping has a learning curve. Using Hiberate
for a "quick" mapping isn't going to happen unless you're already familiar
with it. And if the POJO has interesting relationships, like a Map/Set of
associated objects, you'll want to make sure you understand if you want to
lazy-load or eager-load those associations. Both have value depending on the
context of how you're using the POJO.

I may be missing something here but is JDBC not an option?
