In this article, we study the existence of a classical solution of semilinear elliptic BVP involving gradient term of the type -Delta u = g(u) + psi (del u) + f in Omega, u = 0 on partial derivative Omega, where Omega is a (not necessarily bounded) domain in R-n, n >= 2 with smooth boundary partial derivative Omega. f is an element of C-loc(0,alpha) ((Omega) over bar); 0 < alpha < 1, psi is an element of C-1 (R-n, R) and g satis fi es certain conditions (well known in the literature as \ jumping nonlinearity").
