Five exact spectral-function sum rules for vector currents are presented. A discrepancy between the Weinberg sum rules and the leptonic decays of the J/psi vector meson is resolved. This provides a concrete example illustrating the usefulness of the asymptotically-free-field-theory approach to formulate spectral-function sum rules.
