The elementary constituents of hadronic matter (quarks, anti-quarks, gluons) manifest themselves experimentally in the form of jets of particles. We investigate the precision with which the energy of these fragmenting objects can be measured. The relative importance of the instrumental measurement precision and of the jet algorithm is assessed. We also evaluate the "energy flow" method, in which the information from a charged-particle tracker is combined with that from a calorimeter in order to improve the jet energy resolution.
