  Using a recently developed light-front spectator model that incorporates
gluon, where the light-front wave functions are modeled from the soft-wall
AdS/QCD prediction, we examine the leading twist gluon generalized parton
distributions (GPDs) inside the proton. We derive the chirally even and odd
distributions by using the overlap representation of the light-front wave
functions. In terms of GPDs at non-zero skewness, we investigate the entire
three-dimensional representation of gluons. We analyse the gluon impact
parameter distributions at $\xi=0$ using the Fourier transform of GPDs. We
address the total angular momentum contribution of the gluons by using the Ji's
sum rule and also give our predictions for both the canonical and kinetic
orbital angular momentum in the light-cone gauge.
