You're missing something as you're creating a new Month() and then calling
result.setMonth(m); however, I don't see the code for setMonth.
I think this is an issue with a getter/setting rather than an issue with
DBUtils.
Can you add debug statements and see what the calls to rs.
getString("monthAbbreviation"), rs.getString("monthName"), and
rs.getInt("monthNo")
return?
