<P>We study the Josephson current through a serial double quantum dot and the associated 0-? transitions which result from the subtle interplay between the superconductivity, the Kondo physics, and the interdot superexchange interaction. The competition between them is examined by tuning the relative strength ?/T(K) of the superconducting gap and the Kondo temperature, for different strengths of the superexchange coupling determined by the interdot tunneling t relative to the level broadening ?. We find strong renormalization of t, a significant role of the superexchange coupling J, and a rich phase diagram of the 0 and ?-junction regimes. In particular, when both the superconductivity and the exchange interaction compete with the Kondo physics (???(K)), there appears an island of ?' phase at large values of the superconducting phase difference.</P>
