Abstract: | The Josephson tunneling current in S-I-S structures where the main current transport channel is resonant tunneling through
an isolated localized state is calculated using the Bogolyubov-de Gennes equations. It is shown that the efficiency of equilibrium
Josephson resonant tunneling is determined only by the ratio of the width of the resonance level to the absolute value of
the order parameter for the superconducting electrodes with arbitrary relationships among the system parameters.
