  In this paper, we explicitly compute the semisimplifications of all Jacquet
modules of irreducible representations with generic L-parameters of p-adic
split odd special orthogonal groups or symplectic groups. Our computation
represents them in terms of linear combinations of standard modules with
rational coefficients. The main ingredient of this computation is to apply
Moeglin's explicit construction of local A-packets to tempered L-packets.
