  We discuss the Josephson effect in strongly spin-polarized ferromagnets where
triplet correlations are induced by means of spin-active interface scattering,
extending our earlier work [Phys. Rev. Lett. 102, 227005 (2009)] by including
impurity scattering in the ferromagnetic bulk and the inverse proximity effect
in a fully self-consistent way. Our quasiclassical approach accounts for the
differences of Fermi momenta and Fermi velocities between the two spin bands of
the ferromagnet, and thereby overcomes an important short-coming of previous
work within the framework of Usadel theory. We show that non-magnetic disorder
in conjunction with spin-dependent Fermi velocities may induce a reversal of
the spin-current as a function of temperature.
