Answer 1

User a simple database table (Section, Key, Value). Add "Version" if you need it, and wrap the entire thing in a simple ConfigurationService class with methods like getInt(String section, String key)

Not a lot of work, and it makes the application code very neat, and tweaking with the configuration very easy.
