In this paper, it is shown that the harmonic Bergman projection P ω h , induced by a radial weight ω, is bounded and onto from \(L^{\infty}(\mathbb{D})\) to the harmonic Bloch space \(\cal{B}_{h}\) - if and only if \(\omega\in \cal{D}\) , which is a class of radial weights satisfying the two-sided doubling conditions. As an application, the bounded and compact positive Toeplitz operators T μ,ω h on the endpoint case weighted harmonic Bergman space \(L^1_{h,\omega}(\mathbb{D})\) are characterized.
