Resonance productions of J/psi pairs in ..pi..p and pp collisions are calculated in a Drell-Yan-type mechanism with gluon fusion via the color vector-dominance model. The calculated cross sections and the longitudinal-momentum distributions are consistent with the ..pi..p..-->..JJX data at p/sub L/ = 150 and 280 GeV/c. They are 20--30 times larger than the perturbative QCD results for qq-bar/gg..-->..JJ. Calculations for the resonance productions of J..omega.., D*D-bar*, Jphi, F(F (, UPSILONUPSILON, UPSILON..omega.., B(B (, UPSILONphi, B/sub s/(B /sub s/(, UPSILONJ, and B/sub c/(B /sub c/( in ..pi..p and pp collisions are also presented.
