The equilibrium Josephson current through a nanoscale multi-level quantum dot
with Rashba or Dresselhaus spin-orbit coupling $\alpha$ has been computed. The
critical current can be drastically modified already by moderate $\alpha$. In
the presence of a Zeeman field, Datta-Das-like oscillatory dependencies on
$\alpha$ are predicted.
