Let ▫$\pi \colon Z \to X$▫ be a holomorphic submersion of a complex manifold ▫$Z$▫ onto a complex manifold ▫$X$▫ and ▫$D \Subset X$▫ a 1-convex domain with strongly pseudoconvex boundary. We prove that under certain conditions there always exists a spray of ▫$\pi$▫-sections over ▫$\bar{D}$▫ which has prescribed core, fixes the exceptional set ▫$E$▫ of ▫$D$▫, and is dominating on ▫$\bar{D} \setminus E$▫. Each section in this spray is of class ▫${\mathcal C}^k(\bar{D})$▫ and holomorphic on ▫$D$▫. As a consequence we obtain several approximation results for ▫$\pi$▫-sections. In particular, we prove that ▫$\pi$▫-sections which are of class ▫${\mathcal C}^k(\bar{D})$▫ and holomorphic on ▫$D$▫ can be approximated in the ▫${\mathcal C}^k(\bar{D})$▫ topology by ▫$\pi$▫-sections that are holomorphic in open neighborhoods of ▫$\bar{D}$▫. Under additional assumptions on the submersion we also get approximation by global holomorphic ▫$\pi$▫-sections and the Oka principle over 1-convex manifolds. We include a result on the existance of proper holomorphic maps from 1-convex domains into ▫$q$▫-convex manifolds.
