  We analyse flows around a rotating black hole and obtain self-consistent
accretion-ejection solutions in full general relativistic prescription. Entire
energy-angular momentum parameter space is investigated in the advective regime
to obtain shocked and shock-free accretion solutions. Jet equations of motion
are solved along the von-Zeipel surfaces computed from the post-shock disc,
simultaneously with the equations of accretion disc along the equatorial plane.
For a given spin parameter, the mass outflow rate increases as the shock moves
closer to the black hole, but eventually decreases, maximizing at some
intermediate value of shock location. Interestingly, we obtain all types of
possible jet solutions, for example, steady shock solution with multiple
critical points, bound solution with two critical points and smooth solution
with single critical point. Multiple critical points may exist in jet solution
for spin parameter $a_s\ge 0.5$. The jet terminal speed generally increases if
the accretion shock forms closer to the horizon and is higher for corotating
black hole than the counter-rotating and the non-rotating one. Quantitatively
speaking, shocks in jet may form for spin parameter $a_s>0.6$ and jet shocks
range between $6r_g$ and $130r_g$ above the equatorial plane, while the jet
terminal speed $v_{{\rm j}\infty} > 0.35{\cm}$ if Bernoulli parameter ${\cal
E}\geq1.01$ for $a_s>0.99$.
