We extract diffractive parton densities from data on diffractive deep inelastic scattering (DIS) and on diffractive photoproduction of jets. We explore the results of several {ital Ans{umlt a}tze} for the functional form of the parton densities. Then we use the fitted parton densities to predict the diffractive production of jets and of W{close_quote}s and Z{close_quote}s in p{bar p} collisions at the Fermilab Tevatron. To fit the photoproduction data requires a large gluon density in the Pomeron. The predictions for the Tevatron cross sections are substantially higher than data; this signals a breakdown of hard-scattering factorization in diffractive hadron-hadron collisions. {copyright} {ital 1999} {ital The American Physical Society}
