  Measurements of the production of jets of particles in association with a Z
boson in pp collisions at sqrt(s) = 7 TeV are presented, using data
corresponding to an integrated luminosity of 4.6/fb collected by the ATLAS
experiment at the Large Hadron Collider. Inclusive and differential jet cross
sections in Z events, with Z decaying into electron or muon pairs, are measured
for jets with transverse momentum pT > 30 GeV and rapidity |y| < 4.4. The
results are compared to next-to-leading-order perturbative QCD calculations,
and to predictions from different Monte Carlo generators based on leading-order
and next-to-leading-order matrix elements supplemented by parton showers.
