  We apply the functional bosonization procedure to a massive Dirac field
defined on a 2+1 dimensional spacetime which has a non-trivial boundary. We
find the form of the bosonized current both for the bulk and boundary modes,
showing that the gauge field in the bosonized theory contains a
perfect-conductor boundary condition on the worldsheet spanned by the boundary.
We find the bononized action for the corresponding boundary modes.
