Preliminary results from the DOe experiment on jet production with rapidity gaps in pp-bar collisions are presented. A class of dijet events with a forward rapidity gap is observed at center-of-mass energies {radical}(s)=1800 GeV and 630 GeV. The number of events with rapidity gaps at both center-of-mass energies is significantly greater than the expectation from multiplicity fluctuations and is consistent with a hard diffractive process. A class of events with two forward gaps and central dijets is also observed at 1800 GeV. This topology is consistent with hard double pomeron exchange.
