It is a well known fact that every embedded symplectic surface
$\Sigma$ in a symplectic
four-manifold
$(X^4,\omega )$ can be made $J$-holomorphic for some almost-complex
structure $J$ compatible with
$\omega$.
In this paper we investigate when such a structure
$J$ can be chosen generically
in the sense of Taubes. The main result is stated
in
Theorem 1.2. As an application of this result we give examples of smooth
and non-empty Seiberg-Witten and Gromov-Witten moduli
spaces
whose associated invariants are zero.
