Jersey currently ships with Jackson 1.5.5 (or at least the latest
glassfish version does). I've found that you can normally just swap the
more recent jackson jar files for the ones used by Jersey without
problems. If you're running glassfish, i'd recommend deleting the
osgi-cache before restarting to make sure the right ones are used and
that if you do an update, you re-replace them...
