We present a search for fJ(2220) production in radiative J/psi-->gammafJ(2220) decays using 460  fb[superscript -1] of data collected with the BABAR detector at the SLAC PEP-II e+e- collider. The fJ(2220) is searched for in the decays to K+K- and KS0KS0. No evidence of this resonance is observed, and 90% confidence level upper limits on the product of the branching fractions for J/psi-->gammafJ(2220) and fJ(2220)-->K+K-(KS0KS0) as a function of spin and helicity are set at the level of 10[superscript -5], below the central values reported by the Mark III experiment.
