We have implemented in the RAPGAP program a previously derived subtraction method for next-to-leading order (NLO) corrections in Monte-Carlo event generators, and we show results for jet production in deep inelastic scattering. At small x_{bj}, NLO corrections are comparable to the LO cross section, because of the large gluon density. We devise a jet observable that is particularly sensitive to the treatment of parton kinematics, which our method is intended to treat correctly. We compare the results of the calculation with LO calculations and with the previously existing treatment of NLO processes in RAPGAP. Substantial corrections to the event distribution are found.
