It is shown that the Josephson current in S−I−S---geometry is zero, if one or both superconductors possess the gap odd over p−pF. For the odd-frequency pairing the Josephson current is zero in case of the tunneling between the traditional and odd-gap superconductor and is finite for the tunneling between two odd-gap superconductors.
