We study the Gross--Pitaevskii equation with a delta function potential, $q \delta_0$, where $|q|$ is small and analyze the solutions for which the initial condition is a soliton with initial velocity $v_0$. We show that up to time $(|q| + v_0^2 )^{-1/2} \log$($1$/$|q|$) the bulk of the solution is a soliton evolving according to the classical dynamics of a natural effective Hamiltonian, $(\xi^2 + q \, \sech^2 ( x ) )$/$2$.
