We theoretically study the Josephson current through a half-metallic ferromagnet between two singlet superconductors. The magnon-assisted electron tunneling across the interface induces a triplet pairing correlation in the half-metallic ferromagnet through which the Josephson current flows between the superconductors. It is shown that the Josephson current is pumped by the coherent precession of the magnetization, and is controllable by use of ferromagnetic resonance effect in a ferromagnetic Josephson junction.
