We present a review of mechanisms responsible for the long-range Josephson transport in ballistic hybrid structures superconductor/ferromagnet/superconductor (SFS) with the exchange field modulated either in coordinate or momentum space. These mechanisms are based on the suppression of the destructive interference of electronic and hole waves in the ferromagnet caused by the exchange field. The interference suppression results in the slow decay of the singlet component of the pair correlation function in a ferromagnet and increase in the Josephson current in SFS structures.
