  Following our recent paper on the calculations of diffractive quark jet
production at hadron colliders, we present here the calculations of gluon jet
production at hadron colliders in the two-gluon exchange parameterization of
the Pomeron model. We use the helicity amplitude method to calculate the cross
section formula. We find that for the gluon jet production the diffractive
process is related to the differential off-diagonal gluon distribution function
in the proton. We estimate the production rate for this process at the Fermilab
Tevatron by approximating the off-diagonal gluon distribution function by the
usual diagonal gluon distribution.
