  Jets and outflows must be produced directly from accretion disks and inflows,
especially when the central gravitating objects are compact, such as neutron
stars and black holes, and themselves are {\it not} mass losing. Here, we
review the formation of jets from advective inflows. We show that the
centrifugal pressure supported boundary layer (CENBOL) of the black holes may
play crucial role in producing outflows. CENBOL is not present in Keplerian
disks. Thus energetic jet formation is directly connected to sub-Keplerian
flows close to compact objects.
